Hello
I have a set of sparse matrices (A1, A2, ...) , and need to generate a larger matrix B with these as submatrices. I do not know the precise sparse layouts of the A's (only that each row has one or two non-zero values), and extracting all values to copy into B seems incredibly wasteful. How can I make use of the sparsity to solve this efficiently?
