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
