Parameters
pSrc |
Pointer to the source vector. |
val |
The scalar value used to multiply each element of the source vector. |
pDst |
Pointer to the destination vector. |
pSrcDst |
Pointer to the source and destination vector for in-place operation. |
len |
The number of elements in the vector |
scaleFactor |
Scale factor, refer to Integer Scaling. |
Description
This function multiplies each element of the vector pSrc by a value val and stores the result in pDst.
The in-place flavors of ippsMulC multiply each element of the vector pSrcDst by a value val and store the result in pSrcDst.
The function flavor with Low suffix in its name requires that each value of the product pSrc*val does not exceed the Ipp32s data type range.
The function flavors with Sfs suffix perform scaling of the result value in accordance with the scaleFactor value. If the output value exceeds the data range, the result is saturated.
Return Values
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 0. |
