Parameters
- length
- Number of samples in the Hilbert transform.
- hint
- Option to select the algorithmic implementation of the transform function (DFT). The values for thehintargument 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 isNULL.
- ippStsSizeErr
- Indicates an error whenlengthis less than, or equal to 0.
