HilbertInit

Initializes the Hilbert transform structure.

Syntax

IppStatus ippsHilbertInit_32f32fc(int length, IppHintAlgorithm hint, IppsHilbertSpec* pSpec, Ipp8u* pBuffer);

IppStatus ippsHilbertInit_64f64fc(int length, IppHintAlgorithm hint, IppsHilbertSpec* pSpec, Ipp8u* pBuffer);

Domain Dependencies

Headers: ippcore.h, ippvm.h

Libraries: ippcore.lib, ippvm.lib

Parameters

length	Number of samples in the Hilbert transform.
hint	Option to select the algorithmic implementation of the transform function (DFT). The values for the hint argument are described in Flag and Hint Arguments.
pSpec	Pointer to the Hilbert context structure.
pBuffer	Pointer to the work buffer.

Description

This function initializes the Hilbert specification structure pSpec with the following parameters: the length of the transform length, and the specific code indicator hint. Call this function before using the Hilbert transform function ippsHilbert.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when any of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when length is less than, or equal to 0.
