row and column major for BLAS dot

Please explain the need of row and column major for the oneMKL BLAS dot operation. The inputs are just vectors, not matrices. Thank you.

Hi,

Yes, the layout shouldn't affect BLAS level 1 routines. It is just the way the interfaces are implemented.

You can also refer to the below path where the interface is used:

$MKLROOT/include/oneapi/mkl/blas/buffer.hpp

Thanks & Regards,
