hello all,

I am creating a 2-D array that will be used to solve a truss problem. A user will specify certain boundary conditions for the Nodes of the truss. Based on those boundary conditions, certain rows and corresponding columns will be removed from the overall truss array. This will allow calculation of truss forces. I have a loop which goes through the boundary conditions for each node and determines if rows need to be deleted or not. The boundary conditions also specify nodal displacements or loads that will be found.
