OpenLvVision_OpenCv.lvlib:Gemm.vim

Performs generalized matrix multiplication.

The function gemm performs generalized matrix multiplication:

  • Generalized Matrix Multiplication:
    $ \texttt{dst} = \texttt{alpha} \cdot \texttt{src1} \cdot \texttt{src2} + \texttt{beta} \cdot \texttt{src3} $

Where op(X) is X or X^T (transpose of X), depending on the flags:

  • GEMM_1_T: Transpose src1
  • GEMM_2_T: Transpose src2
  • GEMM_3_T: Transpose src3

The function can be replaced with a matrix expression:

dst = alpha * src1 * src2 + beta * src3; // (or using .t() for transposition)

For detailed information, please refer to the OpenCV documentation

Src1 in

first multiplied input matrix that could be real(CV_32FC1, CV_64FC1) or complex(CV_32FC2, CV_64FC2).
