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
