ISFToISP_AMRWB

Performs ISF conversion to ISP.

Syntax

IppStatus ippsISFToISP_AMRWB_16s(const Ipp16s* pSrcIsf, Ipp16s* pDstIsp, int len);

pSrcIsf	Pointer to the ISF input vector of values scaled in range [0:0.5].
pDstIsp	Pointer to the ISP output vector of values scaled in range [-1:1].
len	Number of ISP and ISF.

This function is declared in ippsc.h file. It converts ISF to the ISP coefficients as given by: pDdstIsp[i] = cos(pSrcIsf[i]), i = 0,..., len.

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to zero.
