dgemm

void dgemm(bool transA, bool transB, int M, int N, int K, double alpha, const double * A, int lda, const double * B, int ldb, double beta, double * C, int ldc)

source edit

Double-precision general matrix multiply (GEMM).

Identical contract to sgemm but operates on double buffers and dispatches to cblas_dgemm.

Math

$C_{ij} \leftarrow \alpha \sum_{k=0}^{K-1} A_{ik} B_{kj} + \beta C_{ij}$
