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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
