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.

c2ddbl

Data

The high-dimensional data you want to transform. Each row represents a sample (e.g. an image or measurement) and each column represents a feature. The number of columns must match the dimensions of the training data used to calculate the Mean and Eigenvectors.

c2ddbl

Result in

Reuse a previously created array to enhance performance.

    cdbl

c2ddbl

Mean

The Mean Vector calculated by the PCA Compute function. It is used to center the data before projection.

    cdbl

c2ddbl

EigenVectors

The Eigenvectors (Principal Components) calculated by the PCA Compute function.

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.

i2ddbl

Result out

The result of the projection. The data is now represented in the principal component space (compressed).
