OpenLvVision_OpenCv.lvlib:MulTransposed.vim

Calculates the product of a matrix and its transposition.

The function cv::mulTransposed computes the product of src and its transpose. Depending on the flag aTa, the result is:

$ \texttt{dst} = \texttt{scale} \cdot (\texttt{src}-\texttt{delta})^T(\texttt{src}-\texttt{delta}), \quad \text{if } aTa = \text{true} $
$ \texttt{dst} = \texttt{scale} \cdot (\texttt{src}-\texttt{delta})(\texttt{src}-\texttt{delta})^T, \quad \text{otherwise} $

The function is commonly used for covariance matrix computation. When delta = 0, it can serve as a faster alternative to the general matrix product A * B when B = A'.

error in

error in can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

    		status

    status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

Src

input single-channel matrix. Note that unlike gemm, the function can multiply not only floating-point matrices.

Dst

dst output square matrix.

Delta

Optional delta matrix subtracted from src before the multiplication. When the matrix is empty ( delta=noArray() ), it is assumed to be zero, that is, nothing is subtracted. If it has the same size as src, it is simply subtracted. Otherwise, it is "repeated" (see repeat ) to cover the full src and then subtracted. Type of the delta matrix, when it is not empty, must be the same as the type of created output matrix. See the dtype parameter description below.

cbool

aTa

Flag specifying the multiplication ordering.

cdbl

Scale

Optional scale factor for the matrix product.
