Text value in an interference matrix

Hello everyone,
First I would like to apologize for this obscure title. If you have any suggestion, i'll take it.

I have data that presents itself in two columns. The first column is what I call the "systems", the second one can be the "features".
For each system (S1, S2, S3, ...) there is one or more features associated (F1, F2, F3, ...).

Ex:

System	Feature
S1	F1
S1	F2
S1	F3
S2	F1
S2	F4

My colleague wants to display which system has different associations of two features. He thought about the output as a table with n lines and n columns (n being the number of features). Then at each intersection, there would be the list of systems that has this association of features.
For example, with the previous the table the result would be like so :

Since S1 and S2 both have F1 in common, they both end up in the F1-F1 cell.
And because only S1 has F2 and F1, it's the only value in F2-F1.

We both got stumped by this problem and couldn't find an easy solution.

Do you see any way we could approach this?

Thanks.

Hello Sandym
Thank you for your answerm i had a gut feeling pivot could help but i played with the options a little and i must be missing out on something.
I can't display the system names, only operations on the amount of systems.
Is there any way to display the strings ?
Thanks !

insert Pivot Table but use

in Data Model duplicate Feature column

next add Measure to the table

then set Measure

next add Feature to the ROWS area, duplicated column to the COLUMNS area and Measure to the VALUES area

that's all folks

Hello Sandy and thank you for the detailed answer
However it looks like the pivot table only populates the diagonal?
For example, I will only see the systems that share the F1 feature, but I will not see the ones that have F2 and F1 in common.

If you look at my first post, you can see the end result does not only have values in the diagonal.

I should have said so after your first post, my bad

F1 to F1 is S1, S2
F2 to F2 is S1
and so on

if you have the same headers and labels the result will be diagonal, this is your choice from post#1
