OpenLvVision_OpenCv.lvlib:Eigen.vim

Calculates eigenvalues and eigenvectors of a symmetric matrix.

The function cv::eigen calculates eigenvalues only, or both eigenvalues and eigenvectors of a symmetric matrix src:

$ \texttt{src} \cdot \texttt{eigenvectors.row}(i)^T = \texttt{eigenvalues.at<srcType>}(i) \cdot \texttt{eigenvectors.row}(i)^T $

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.

    cbool

    		status

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

    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.

    ci32

    		code

    cstr

    		source

    source describes the origin of the error or warning.

    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.

cOpenLvVision__OpenCv_lvlib_Anythinglvclass

Src in

input matrix that must have CV_32FC1 or CV_64FC1 type, square size and be symmetrical (src ^T^ == src).

cOpenLvVision__OpenCv_lvlib_Anythinglvclass

EigenVector in

output matrix of eigenvectors; it has the same size and type as src; the eigenvectors are stored as subsequent matrix rows, in the same order as the corresponding eigenvalues.

ierrcodeclst

error out

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.

    ibool

    		status

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

    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.

    ii32

    		code

    istr

    		source

    source describes the origin of the error or warning.

    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.

iOpenLvVision__OpenCv_lvlib_Anythinglvclass

Src out

Same as src

iOpenLvVision__OpenCv_lvlib_Anythinglvclass

EigenVector out

output matrix of eigenvectors; it has the same size and type as src; the eigenvectors are stored as subsequent matrix rows, in the same order as the corresponding eigenvalues.

i1ddbl

EigenValues

output vector of eigenvalues of the same type as src; the eigenvalues are stored in the descending order
