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 whenpSrc1,pSrc2orpDstpointer isNULL.
- ippStsSizeErr
- Indicates an error whenlenis 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 results:
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
