Description

hrPrev

HRESULT

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

ipMlModel

ITcVnMlModel*&

Returns the created feature transform (Non-zero interface pointers are reused.)

ipSamples

ITcUnknown*

Container holding a batch of input samples (ContainerType_Vector_Vector_REAL or ContainerType_Vector_Vector_LREAL)

ipClasses

ITcVnContainer*

Class labels corresponding to the input samples (ContainerType_Vector_DINT)
