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, ...).
