weird no const keyword for '*beta' of DSYR2K in mkl_blas.h

Lee__Heungson — Tue, 26 May 2020 01:17:21 GMT

In 'mkl_blas.h'

void DSYR2K(const char *uplo, const char *trans, const MKL_INT *n, const MKL_INT *k,
const double *alpha, const double *a, const MKL_INT *lda, const double *b, const MKL_INT *ldb,
double *beta, double *c, const MKL_INT *ldc);

There is no const keyword for '*beta'.

On the other hand, these two have const keyword for '*beta'

void SSYR2K(const char *uplo, const char *trans, const MKL_INT *n, const MKL_INT *k,
const float *alpha, const float *a, const MKL_INT *lda, const float *b, const MKL_INT *ldb,
const float *beta, float *c, const MKL_INT *ldc);

void ZSYR2K(const char *uplo, const char *trans, const MKL_INT *n, const MKL_INT *k,
const MKL_Complex16 *alpha, const MKL_Complex16 *a, const MKL_INT *lda,
const MKL_Complex16 *b, const MKL_INT *ldb, const MKL_Complex16 *beta,
MKL_Complex16 *c, const MKL_INT *ldc);

Are there any reasons for this inconsistency?

Because in my development environment, macros are used to deal with different types and these forms should be consistent with each other. But I see some functions don't have const consistency for different types. So it would be more convenient for some users like me if these were fixed in the future release.

Thank you.

Thanks for the issue. We will
