Parameters
- pSrc
- Pointer to the source vector.
- pDst
- Pointer to the destination vector.
- pSrcDst
- Pointer to the source and destination vectorpSrcDstfor the in-place operation.
- len
- Number of elements in the vector.
Description
This function computes the inverse tangent of each element of
pSrc
and stores the
result in the corresponding element of pDst
.The computation is performed as follows:
pDst
[n] =
arctan(pSrc
[n])0
.≤
n < len
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepSrc,pDst, orpSrcDstpointer isNULL.
- ippStsSizeErr
- Indicates an error whenlenis less than or equal to 0.
