Very well, I'll adapt your code to provide bmat/hstack/vstack-like
functionality.
Regarding names, we already have spkron ~= kron and spdiags ~= diag.
I think we'll have to abandon this approach for the proposed functions
since spbmat, sphstack, spvstack are terrible :)
Which is better,
column_stack_sparse
row_stack_sparse
block_matrix_sparse
or
sparse_column_stack
sparse_row_stack
sparse_block_matrix
I prefer the XXX_sparse format since it aids tab completion. Suggestions?
