mkl_dcsradd doubt

[JBervel]

Hi,

I am working with the function

mkl_dcsradd(...)

When I pass two matrices like

1 1 1 1 -1 1
0 0 0 0 0 0
0 0 0 0 0 0

the returnedmatrix is:

values:2 0 2
columns: 1 2 3
rowIndex: 1 4 4 4

There is any way to automatically eliminate the zero values returned by the function?

values: 2 2
columns: 1 3
rowIndex: 1 3 33

Thanks

Hi,

MKL doesn't have such functionality.

Do you feel this feature (like eliminating zero entries from sparse formats) is worth including in some of the next MKL releases?

Regards,

Yes, it would be good for my work.

Thanks for the response.

but You have to take into account that this functionality would negatively affects on the performance of this routine.
