pSrc |
Pointer to the source vector. |
pDst |
Pointer to the destination vector. |
pSrcDst |
Pointer to the source and destination vector for in-place operations. |
len |
Number of elements in the vector |
scaleFactor |
Scale factor, refer to Integer Scaling. |
This function computes the square of each element of the vector pSrc, and stores the result in pDst. The computation is performed as follows:
pDst[n] = pSrc[ n]2
The in-place flavors of ippsSqrcompute the square of each element of the vector pSrcDst and store the result in pSrcDst. The computation is performed as follows:
pSrcDst[n] = pSrcDst[ n]2
When computing the square of an integer number, the output result can exceed the data range and become saturated. To get a precise result, use the scale factor.
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when the pSrc, pDst, or pSrcDst pointer is NULL. |
ippStsSizeErr |
Indicates an error when len is less than or equal to zero. |
