OpenLvVision_OpenCv.lvlib:PCA.lvclass:PCA CreateRetainedVariance .vi

Object by reference!

The default constructor initializes an empty PCA structure. The other constructors initialize the structure and call PCA::operator()()

cerrcodeclst

error in (no error)

The error in cluster 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.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    cbool

    		status

    The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    ci32

    		code

    The code input identifies the error or warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    cstr

    		source

    The source string describes the origin of the error or warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

c2ddbl

Data

input samples stored as matrix rows or matrix columns.

    cdbl

    		Numeric

c2ddbl

Mean

optional mean value; if the matrix is empty (noArray()), the mean is computed from the data.

    cdbl

    		Numeric

cenum

Flags

DATA_AS_ROW =indicates that the input samples are stored as matrix rows

DATA_AS_COL = indicates that the input samples are stored as matrix columns

USE_AVG

cdbl

retainedVariance

Percentage of variance that PCA should retain. Using this parameter will let the PCA decided how many components to retain but it will always keep at least 2.

ierrcodeclst

error out

The error out cluster passes error or warning information out of a VI to be used by other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    ibool

    		status

    The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    ii32

    		code

    The code input identifies the error or warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

    istr

    		source

    The source string describes the origin of the error or warning.

    The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
