Hi,
I have three SparseMatrix objects already created, M, S, and T. I'd
like to combine them into one BlockSparseMatrix of the form A = [M, S;
T, M]. All of these matrices are the same size (square) and have the
same sparsity patterns. I've read through the documentation on
BlockSparseMatrix and I can't quite figure out how to do this. I'm sure
I'm missing something obvious (unless what I want to do is impossible!),
but can someone point me to the methods I need to use?
I'd like to do this so I can use SparseDirectUMFPACK to solve Ax = b
with the above A. The documentation says that SparseDirectUMFPACK
should work with BlockSparseMatrix objects too.
Thank you!
Best,
-J
