Header:	FIL.h
Namespace:	fil

Applies previously obtained Principal Component Analysis (PCA) transformation coefficients to new data.

void fil::ApplyPCATransform
(
	const fil::Matrix& inMatrix,
	const fil::PCAModel& inPCAModel,
	fil::Matrix& outTransformedMatrix
)

Name	Type	Description
inMatrix	const Matrix&	Input data with variables in columns and examples in rows.
inPCAModel	const PCAModel&	Previously created PCA model to apply to data provided in inMatrix.
outTransformedMatrix	Matrix&	Transformed inMatrix.

List of possible exceptions:

Error type	Description
DomainError	Malformed inPCAModel - MeanVector and StandardDeviationVector are not row-vectors in ApplyPCATransform.
DomainError	Malformed inPCAModel - MeanVector and StandardDeviationVector have to have the same length in ApplyPCATransform.
DomainError	PCAModel does not match - inMatrix column count does not match in ApplyPCATransform.
DomainError	PCAModel does not match - PCAFeatureVector dimensions does not correspond to inMatrix dimensions in ApplyPCATransform.
DomainError	PCAModel does not match - StandardDeviationVector length is different then inMatrix column count in ApplyPCATransform.
