Parameters
- val
- Scalar value from which vector elements are subtracted.
- pSrc
- Pointer to the source vector.
- pDst
- Pointer to the destination vector.
- pSrcDst
- Pointer to the vector whose elements are to be subtracted from the valuevalin case of the in-place operation. The destination vector which stores the result of the subtraction.val-pSrcDst[n]
- len
- Number of elements in the vector
- scaleFactor
- Scale factor, refer to Integer Scaling.
Description
This function subtracts each element of the vector
pSrc
from a value val
and stores the result in pDst
.The in-place flavors of
ippsSubCRev
subtract each element of the vector pSrcDst
from a value val
and store the result in pSrcDst
. Functions with
Sfs
suffixes perform scaling of the result value in accordance with the scaleFactor
value. If the output value exceeds the data range, the result becomes saturated. Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepSrc,pDst,or pSrcDstpointer isNULL.
- ippStsSizeErr
- Indicates an error whenlenis less than or equal to 0.
