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.
