does cblas level 3 support integer data?

Hi

I was wondering if I can use matrices with integer data with CBLAS level 3 routines. Is it possible to do this? If so, how ? Please let me know.


thanks

No way. You need to convert the input data to floating-point representation. Julien.

Yep you cast your int matrix element by element in double (or single) format. Then you call CBLAS and the output will be double (or single), then you cast back to int. There is no igemm :) in the BLAS.
