Parameters
- pSrc
- Pointer to the source vector.
- pSrcDst
- Pointer to the source and destination vector for in-place operations.
- vSub
- Subtrahend value.
- vDiv
- Denominator value.
- pDst
- Pointer to the vector which stores the normalized elements.
- len
- Number of elements in the vector
- scaleFactor
- Scale factor, refer to Integer Scaling .
Description
This function subtracts
vSub
from elements of the input vector
pSrc
(
pSrcDst
for in-place operations), divides the differences by
vDiv
, and stores the result in
pDst
(
pSrcDst
for in-place operations). The computation is performed as follows:
pDst
[n] = (
pSrc
[n] -
vSub
)/
vDiv
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when thepSrcorpDstpointer isNULL.
- ippStsSizeErr
- Indicates an error whenlenis less than or equal to 0.
- ippStsDivByZeroErr
- Indicates an error whenvDivis equal to 0 or less than the minimum floating-point positive number.
