.. ocv:cfunction:: void cvGEMM( const CvArr* src1, const CvArr* src2, double alpha, const CvArr* src3, double beta, CvArr* dst, int tABC=0)
:param src1: first multiplied input matrix that should have ``CV_32FC1``, ``CV_64FC1``, ``CV_32FC2``, or ``CV_64FC2`` type.
:param src1: first multiplied input matrix that could be real(``CV_32FC1``, ``CV_64FC1``) or complex(``CV_32FC2``, ``CV_64FC2``).
:param src2: second multiplied input matrix of the same type as ``src1``.
@ -1246,6 +1246,8 @@ The function performs generalized matrix multiplication similar to the ``gemm``
\texttt{dst} = \texttt{alpha} \cdot \texttt{src1} ^T \cdot \texttt{src2} + \texttt{beta} \cdot \texttt{src3} ^T
In case of complex (two-channel) data, performed a complex matrix multiplication.
The function can be replaced with a matrix expression. For example, the above call can be replaced with: ::
dst = alpha*src1.t()*src2 + beta*src3.t();
