Domain Dependencies

Headers: ippcore.h, ippvm.h

Libraries: ippcore.lib, ippvm.lib

Parameters

pSrc

Pointer to the source vector.

val

Scalar value used to increment each element of the source vector.

pDst

Pointer to the destination vector.

pSrcDst

Pointer to the source and destination vector for the in-place operation.

len

Number of elements in the vector.

scaleFactor

Scale factor, refer to Integer Scaling.

rndMode

Rounding mode, the following values are possible:

ippRndZero floating-point values are truncated to zero

ippRndNear floating-point values are rounded to the nearest even integer when the fractional part equals 0.5; otherwise they are rounded to the nearest integer

ippRndFinancial floating-point values are rounded down to the nearest integer when the fractional part is less than 0.5, or rounded up to the nearest integer if the fractional part is equal or greater than 0.5.

Description

This function adds a value val to each element of the source vector pSrc, and stores the result in the destination vector pDst.

The in-place flavors of ippsAddC add a value val to each element of the vector pSrcDst, and store the result in pSrcDst.

Functions with Sfs suffixe 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 zero.
