What form should the multiplication result be in? (both)

12:58pm Sat 24th Aug, ANONYMOUS

Hi, For the project, I was wondering what form the compressed multiplication result should be in? Should I output a full 100000x100000 matrix or a compressed matrix? Thanks

I would say for N = 100000, it is more efficient to store the result in an uncompressed form. When N is large, even if the original matrix has a low non-zero rate, the resulting matrix is likely to have a non-zero rate close to 1.
