does mkl support mixed-precision for c interface?

Does mkl support mixed-precision for c interface? Just like a complex matrix multiply a double vector.

Is it still ok for this mkl_sparse_mv? here alpha and beta must be complex according to the annoucement.

Hi dongw,

Unfortunately the Inspector Executor Sparse BLAS C/Fortran APIs do not support mixed precision. At this time, you must use the same data type for all appropriate arrays and constants like alpha and beta.

Best,

Spencer

Thanks for posting in Intel Communities.

This is to kindly inform you that oneMKL interface doesn't support mixed precision as of now.
