question on call mkl_zcoosymv

Is this subroutinee mkl_zcoosymv (coordinate format for sparse matrices and one based indexing) for Hermitian matrix-vector operation ? The help document groups both real and complex matrix vector operations under symmetric matrices. It does NOT say specifically for complex matrices are Hermitian. Just want to make sure.

mkl_zcoosymv wors for symmetric matrixes only, therefore Hermit matrixes doesn't support.
But another Sparse BLAS routine "mkl_zcoomv" supports Hermit matrix. You have to set matdescra(1) = "H" and then you can use hermit matrix for that.
