Multiplication of Sparse complex matrix and a full matrix

Let A be a sparse matrix and B be a full matrix . C = A.*B. Will multiplication of elements of B corresponding to the zero elements of A be eliminated?

" Will multiplication of elements of B corresponding to the zero elements of A be eliminated?"

What do you mean by "eliminated"? This is not a MATLAB term that I am familiar with.

[D_coder]

it means will the mutliplication with zero be saved? Or still the multiplication will occur

Answer 1

[Walter Roberson]

The sparse multiplication will skip multiplying the elements that are known to be 0 in the sparse matrix.
