Type Alias Zgemm64FnPtr 

pub type Zgemm64FnPtr = unsafe extern "C" fn(*const i8, *const i8, *const i64, *const i64, *const i64, *const Complex<f64>, *const Complex<f64>, *const i64, *const Complex<f64>, *const i64, *const Complex<f64>, *mut Complex<f64>, *const i64);

BLAS zgemm function pointer type (ILP64: 64-bit integers)

Signature matches Fortran BLAS zgemm (ILP64):

void zgemm_(char *transa, char *transb, long long *m, long long *n, long long *k,
            void *alpha, void *a, long long *lda, void *b, long long *ldb,
            void *beta, void *c, long long *ldc);
