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
