Detailed Description
The function performs generalized matrix multiplication similar to the gemm functions in BLAS level 3: \(D = \alpha*AB+\beta*C\)
- Parameters
-
src1 pointer to input \(M\times N\) matrix \(A\) or \(A^T\) stored in row major order. src1_step number of bytes between two consequent rows of matrix \(A\) or \(A^T\). src2 pointer to input \(N\times K\) matrix \(B\) or \(B^T\) stored in row major order. src2_step number of bytes between two consequent rows of matrix \(B\) or \(B^T\). alpha \(\alpha\) multiplier before \(AB\) src3 pointer to input \(M\times K\) matrix \(C\) or \(C^T\) stored in row major order. src3_step number of bytes between two consequent rows of matrix \(C\) or \(C^T\). beta \(\beta\) multiplier before \(C\) dst pointer to input \(M\times K\) matrix \(D\) stored in row major order. dst_step number of bytes between two consequent rows of matrix \(D\). m number of rows in matrix \(A\) or \(A^T\), equals to number of rows in matrix \(D\) n number of columns in matrix \(A\) or \(A^T\) k number of columns in matrix \(B\) or \(B^T\), equals to number of columns in matrix \(D\) flags algorithm options (combination of CV_HAL_GEMM_1_T, ...).
