I suppose you could use dgemm with alpha = 0. and dummy arguments for
A and B. I don't know if there would be any advantage in doing the
calculation this way.
The C declaration corresponding to the Fortran subroutine is
/* Level 3 BLAS */
/* DGEMM - perform one of the matrix-matrix operations */
/* C := alpha*op( A )*op( B ) + beta*C, */
void F77_NAME(dgemm)(const char *transa, const char *transb,
const int *m, const int *n,
const int *k, const double *alpha,
const double *a, const int *lda,
const double *b, const int *ldb,
const double *beta, double *c, const int *ldc);
