Prepare Element
Dear all
I try to find A that A is function that have Node and Member_Node as variable as Pic&File attachment.
Thank you
I was not sure if the matrix Member_Node would always have exactly two columns, so I made a function which can also deal with arbitrary dimensions of Member_Node:
In case you want Label_Node and also the result to be simple matrices rather than the nested ones you had shown, you may just change the vector index for the row selector.
Changes for simple Input matrix in yellow
Change for simple output matrix in red
