    How to create a new array with rows that have same values in different arrays

    Hi,

    I need help to write a macro that creates a new 2D array with rows that have same values in 2 2D arrays.

    For example:

    Array1
    1 2
    3 4
    5 6
    7 8
    9 10

    Array2
    1 2
    2 3
    4 5
    5 6
    7 8

    Array3 (new 2D array to be created)
    1 2
    5 6
    7 8

    Thanks.

    Re: How to create a new array with rows that have same values in different arrays

    Jindon,

    Sorry. Let me explain better.

    I have 2 2D arrays (Array1 and Array2) and I need to create a new array (Array3) based on the analysis of these 2 arrays (rows with same values).

    The code I need should be like:

    Hi,

    could be easier with cells rather than arrays just with Excel basics …
    With arrays you need to test each 'row' via a loop for example.

    Re: How to create a new array with rows that have same values in different arrays

    Hi, Marc L,

    The actual arrays (Array1 and Array2) have 1 million rows each.

    Other question: even if I use 2 ranges, I need to loop one range by the other, right?

    All I need is a fast macro to analyze 2 ranges (or 2 arrays) with 1 million rows each and create a new range (or new array) with rows that have same values. The result (Array3 or a third range) should be written in Range("I1").

    Array1 = Range("A1:B1000000").Value
    Array2 = Range("E1:F1000000").Value
    Write Array3 (or the result from range comparison) in Range("I1")

    Thanks.

    Cool Try this …


    For sorted ranges an optimization should be to work from columns concatenations …

    Anyway for sorted arrays only, a VBA beginner starter :

    PHP Code: 
    Sub Demo1()
            
    = [{1,2;3,4;5,6;7,8;9,10}]
            
    = [{1,2;2,3;4,5;5,6;7,8}]
            
    ReDim X(1 To UBound(V))
            
    L& = 1
        
    For R& = 1 To UBound(V)
            Do
                If 
    W(L1) = V(R1Then
                    
    If W(L2) = V(R2Then
                        N
    & = N& + 1
                        X
    (N) = Array(V(R1), V(R2))
                        If 
    UBound(WThen L 1: Exit Do Else Exit For
                    
    End If
                ElseIf 
    W(L1) > V(R1) Or UBound(WThen
                    
    Exit Do
                
    End If
                    
    1
            Loop
        Next
        
    If N Then
            ReDim Preserve X
    (1 To N)
            
    Application.Index(XEvaluate("ROW(1:" ")"), [{1,2}])
        Else
            
    Split("")
        
    End If
            
    Stop    ' see what X contains
    End Sub

    Exclamation Re: How to create a new array with rows that have same values in different arrays


    Jindon,

    to avoid errors from one million rows data I would add a delimiter within the concatenation !
    As comparing as it is for example {1,11} and {11,1} returns the same concatenation - 111 - but for different pairs …

    Another point : as worksheet function Transpose is limited to 65K rows so it could be an issue if more than 65K pairs are matching !

    Here is the code tested for 10 rows. The code does not restrict the number of rows and number of matching rows.
    Change !0 to the required number. First trail on a copied file. Array need not be sorted one.

    Re: How to create a new array with rows that have same values in different arrays

    Hi JOAO12,

    I was looking into this but had a question about duplicity.
    Array1
    1 2
    3 4
    5 6
    7 8
    9 10
    A A
    B B
    B B

    Array2
    1 2
    2 3
    4 5
    5 6
    7 8
    A A
    B B

    C C
    Array3 (new 2D array to be created)
    1 2
    5 6
    7 8
    Would you get:
    A A
    B B


    OR (Because it exist in both columns)
    A A
    B B
    B B


    Edited:
    Please see attached on a set for 10,000 random numbers. Takes about a minute to run 10,000 data.
    NOTE: This code does not accommodate for duplicity.

    Re: How to create a new array with rows that have same values in different arrays

    Hi D13L,

    Both Array1 and Array2 have 5 rows and 2 columns and are filled with numbers.

    I need to create a new array (Array3) with rows that exist in both arrays (Array1 and Array2), that is:

    {1, 2} = First row in Array1 = First row in Array2
    {5, 6} = Third row in Array1 = Forth row in Array2
    {7, 8} = Forth row in Array1 = Fith row in Array2

    Thanks for the code.

    Re: How to create a new array with rows that have same values in different arrays

    I apologize, I must not be explaining myself well.
    My code checks Arr1 and loops through Arr2 until it finds a match:

    I've added a scenario to your example:

    Array1
    1 2
    1 2
    1 2
    3 4
    5 6
    7 8
    9 10

    Array2
    1 2
    1 2
    0 0
    2 3
    4 5
    5 6
    7 8

    Array3 (new 2D array to be created)
    1 2 <=== Does this get 2 or 3? (My code would produce 3, does not account for duplicity which array1 is top level for match)
    5 6
    7 8

    Edit:
    Hope this clarified it a bit better. I've added an temp array that would account for duplicates but have not implemented it in. Wasn't sure if duplicity was a factor.

    Re: How to create a new array with rows that have same values in different arrays

    D13L,

    Now I understand the scenario you mentioned, but in Array3 (arr3) row {1, 2} needs to appear just once (no need to appear twice or three times).

    For now, each array has no duplicate rows. So, for now I am not concerned with it. The goal is that the code runs as fast as possible.

    Thanks.

    The drawback with Dictionary object is it is fast until it reaches a number of elements then it becomes slower than a VBA Collection !
    This critical threshold is between 400K & 500K elements.
    We could proceed to some tests at least with an attachment saved as binary (.xlsb) …

    Re: How to create a new array with rows that have same values in different arrays

    Hi,

    I edited post#16 which should be the corrected code. This is utilizing the "remove Duplicate" in excel.
    Logic

    1) Concatenate array1 then remove duplicate within array1
    2) Concatenate array2 then remove duplicate within array2
    3) Stack Array1 and Array Then remove duplicate with stacked array1 and array2
    4) The ending result would be array3

    Tried this with 1 mil random decimal numbers. Finished it in a couple of seconds.

    Would you mind checking it out.

    Re: How to create a new array with rows that have same values in different arrays

    Hi Marc L,

    I'm assuming this comments is for me (D13L).

    I'm self taught and really chose logic based on my limited knowledge. I really would appreciate some positive criticism. I wasn't sure if my method has any flaws since I learn by jumping in the lion's den .

    I'd really appreciate if you can define the flaw. (I liked your perception above post really insightful and taught me well, like how my first attempt used the array loop which was really slow)

    Thanks

    Ohhh no. Sorry everyone. The code is no good. I forgot the most important step. COMPARE THE 2 ARRAYS.

    Re: How to create a new array with rows that have same values in different arrays

    Looks like I can actually utilize the program still by...
    LOGIC:
    1) Concatenate array1 then remove duplicate within array1
    2) Concatenate array2 then remove duplicate within array2
    3) Stack Array1 and Array2 Then remove duplicate with stacked array1 and array2

    4) #3 becomes arrayTemp
    5) Sort arrayTemp A-Z
    6) Sort the smallest of the two array1/array2
    7) Compare
    8) And the result should be array3


    The only issue I find with this is; Does the original poster allows sorting?

    DL13, as within the initial post the arrays are sorted but its 'explanation' seems not closed to its real need and not what any forum expects for …

    So if you do not want to waste any more time, just wait at least for a complete & crystal clear explanation
    - what is the destination of the result array ? If back to a new range, the array can be avoided … -
    and as a bonus with an xlsb workbook containing at least 70K matching pairs …

    Re: How to create a new array with rows that have same values in different arrays

    MarcL,

    Thanks for the suggestion. I'm REALLY ENJOYING this so I kept on going.
    Also my logic above is completely flawed from #3-#8

    New logic
    1) Concatenate array1 then remove duplicate within array1
    2) Concatenate array2 then remove duplicate within array2
    3) removed array1 special chara(~ and .) and set to a cell range Creates a long number
    4) removed array2 special chara(~ and .) and set to a cell range Creates a long number
    5) Compare(MATCH) short array to the large array ==> gives me row number. THIS PORTION I AM NOT CONFIDENT ON ESPECIALLY IF THE Original Poster HAS A DIFFERENT SPECIAL CHAR. CODE DEPENDENT THAT IT IS A LONG NUMBER NOT A STRING
    6) Sort it to A-Z ==> isolate blanks
    7) Used Index to match to the original concatenate array
    8) Split special character to the remainder array. THIS BECOMES ARRAY3


    I tested it on 1 million random numbers(1-1000). Program ran around 200 seconds.
    Hopefully this is good. This is my final attempt, I can't logically break it down any further.

    Anybody interested in reviewing, I'd be glad for some constructive criticism. Doing these project, and getting sincere comments is the quickest way for me to learn.

    Re: How to create a new array with rows that have same values in different arrays

    Hi all,

    Sorry for not being able to post this message earlier.

    I would like to thank all of you, Jindon, D13L, Marc L and Kvsrinivasamurthy, for sharing your knowledge.


    D13L,
    Unfortunately, I was not able to run the macro in “multiDim_Dup2nd attempt.xlsm” file. An error message appears, saying that “Run time error 1004 - Autofill Method of Range Class Failed”.


    Jindon,
    Could you please add a variable for last row number in the following line, so that the code looks like:

    Kvsrinivasamurthy,
    Unfortunately, when I tested your code with the actual data, the results did not match the expected results. Is it possible to correct the code? Please see the attached file “Test File – Kvsrinivasamurthy.xlsb”.


    Marc L,
    Your code took only 0.17 seconds to run in a worksheet with 65536 rows, but there was an error when testing with the actual data (subscript out of range). I was unsuccessful trying to fix it. Please see the attached file “Test File - Marc L.xlsb”.

    Thanks

    Re: How to create a new array with rows that have same values in different arrays

    Hi JOAO12,

    It seems like it has auto-calculate off which is unable to copy formula down causing the error1004. I've updated the code to add manual calculate.

    I've ran to your test sample data and it seems to run at around 18 sec.

    I've ran this code on 1 mil random data with decimal points(=RANDBETWEEN(5,25-1)+RAND()) . Ran a little under 200 sec.

    Lightbulb Try this too !


    According to the same attachment the Dictionary way, slightly slower in more than a second :

    PHP Code: 
    Sub Demo2()
      Const 
    "¤"
        
    Dim T!, V(1), C%, R&, N&
            
    Timer
            V
    (0) = [A1].CurrentRegion.Value2
            V
    (1) = [E1].CurrentRegion.Value2
            
    [I1].CurrentRegion.Clear
            C 
    = -(UBound(V(1)) < UBound(V(0)))
        
    With CreateObject("Scripting.Dictionary")
            For 
    1 To UBound(V(C)):  .Item(V(C)(R1) & V(C)(R2)) = Empty:  Next
                C 
    C
            
    For 1 To UBound(V(C))
                If .
    Exists(V(C)(R1) & V(C)(R2)) Then N 1V(C)(N1) = V(C)(R1): V(C)(N2) = V(C)(R2)
            
    Next
               
    .RemoveAll
        End With
        
    If N Then
            
    [I1:J1].Resize(N).Value2 V(C)
            
    Debug.Print "Demo2  : "Format(Timer T"0.000s")
        
    End If
    End Sub

    As your post #30 attachment has only 107K rows maybe none of my both demonstrations is the more appropriate
    so for further tests I need your million rows worksheet …

    Re: How to create a new array with rows that have same values in different arrays

    Hi JOAO12,

    I've updated the code to assume no duplicity and removed redundancy in steps. It runs a little over 9 sec with your 100,00 data sample.

    Runs to over 38 sec with 1,000,000 random data points.

    Note: corrected fill down 'error1004'. Due to auto calculate was off. Added Manual Calculation in code.

    EDITED: Updated Calculate to a specific sheet and Cell range only.

    According to posts #5 & 15 it shoud be achieved in less than 20 sec,
    hoping around 10 sec maybe less as it also depends on the number of matching pairs …

    Hi Marc L,

    Your macro Demo1r (post #32) takes 0.25 seconds to run.

    Once again, thank you for sharing your knowledge in this thread.

    Question Re: How to create a new array with rows that have same values in different arrays


    0.25 on your sample of 107K (0.37 on my old tests laptop) but not for one million rows ?!

    If for one million rows how many matching rows in the result ?

    Hi Marc L,

    For 1,000,000 rows, with 1,000,000 matching rows, it takes 1.38 second.

    Question Re: How to create a new array with rows that have same values in different arrays


    Whaou ! Thanks !

    I'm a bit surprised of 1 000 000 matching rows so this is the result in columns I:J ?
