Conj
Performs element by element conjugation of the vector.
Syntax
IppStatus ippsConj_32fc_A24 (const Ipp32fc* pSrc, Ipp32fc* pDst, Ipp32s len);
IppStatus ippsConj_64fc_A53 (const Ipp64fc* pSrc, Ipp64fc* pDst, Ipp32s len);
Include Files
ippvm.h
Domain Dependencies
Headers: ippcore.h
Libraries: ippcore.lib
Parameters
pSrc |
Pointer to the source vector. |
pDst |
Pointer to the destination vector. |
len |
Number of elements in the vectors. |
Description
This function performs element by element conjugation of the vector pSrc and stores the result in the corresponding element of the vector pDst.
For single precision data:
function flavor ippsConj_32fc_A24 guarantees 24 correctly rounded bits of significand, including the implied bit, with the maximum guaranteed error within 1 ulp.
For double precision data:
function flavor ippsConj_64fc_A53 guarantees 53 correctly rounded bits of significand, including the implied bit, with the maximum guaranteed error within 1 ulp.
The computation is performed as follows:
pDst[n] = CONJ(pSrc[n]), 0 ≤ n < len.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when pSrc1, pSrc2 or pDst pointer is NULL. |
ippStsSizeErr |
Indicates an error when len is less than or equal to 0. |
Example
The example below shows how to use the function ippsConj.
IppStatus ippsConj_32fc_A24_sample(void) { const Ipp32fc x[2] = {{+2.885,-1.809}, {-0.543,-2.809}}; Ipp32fc y[2]; IppStatus st = ippsConj_32fc_A24( x, y, 2 ); printf(" ippsConj_32fc_A24:\n"); printf(" x = %+.3f%+.3f*i %+.3f%+.3f*i \n", x[0].re, x[0].im, x[1].re, x[1].im); printf(" y = %+.3f%+.3f*i %+.3f%+.3f*i \n", y[0].re, y[0].im, y[1].re, y[1].im); return st; }
Output:
ippsConj_32fc_A24: x = +2.885-1.809*i -0.543-2.809*i y = +2.885+1.809*i -0.543+2.809*i
