RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

wrap PCA::operator() and add eigenvalues output parameter

mean

Input/output value, modified by the native operation. mean argument (Mat).

eigenvectors

Output destination, filled by the native operation. eigenvectors argument (Mat).

eigenvalues

Output destination, filled by the native operation. eigenvalues argument (Mat).

retainedVariance

retained variance argument (number).
