GetFeatureScales

Calculate the scaling parameters for each feature in the input samples based on the scaling type.

Syntax

Definition:

HRESULT GetFeatureScales(
    HRESULT                 hrPrev,
    ITcVnContainer*         ipSamples,
    ITcVnContainer*&        ipScales,
    ETcVnFeatureScalingType eFeatureScalingType
)

Parameters

Name	Type	Description
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
ipSamples	ITcVnContainer*	Container holding input sample(s) (ContainerType_Vector_REAL, ContainerType_Vector_LREAL, ContainerType_Vector_Vector_REAL or ContainerType_Vector_Vector_LREAL)
ipScales	ITcVnContainer*&	Returns a container with the scaling parameters for each feature (Vector_REAL or Vector_LREAL depending on the type of ipSamples).
eFeatureScalingType	ETcVnFeatureScalingType	Feature scaling type
