Hi,
What is the best way to find out if the nonzero structure of two
sparse matrices is the same (assume both have the same type,
compressed_matrix<T,O>)?
On a similar note, if they aren't, I need this type of query: say A
and B are sparse, slightly different structure. Say C = A + B also
sparse. Iterating over C.value_data()[i], I'd like to find out the
corresponding indices (i,j) into A and B.
Thanks!
