parameters problem of GEMM (can a, c be the same pointer?)

Postby gzygzy9211 » Tue Jul 22, 2014 4:34 am

I am confused that if in the function GEMM:
it is about the three matrix param (a, b, c, all are float* if it is SGEMM).
I am not sure weather the "a" and "c" can be the same pointer, and so are "b" and "c".

This problem come to me because I found that SYRK can not do this (a and c are the same pointer)

And ...... what about the other functions?

:? :? :? :?
