ReplaceNAN

Replaces not-a-number (NaN) values of vector elements with a constant value.

Syntax

IppStatus ippsReplaceNAN_32f_I(Ipp32f* pSrcDst, int len, Ipp32f value);

IppStatus ippsReplaceNAN_64f_I(Ipp64f* pSrcDst, int len, Ipp64f value);

Domain Dependencies

Headers: ippcore.h, ippvm.h

Libraries: ippcore.lib, ippvm.lib

Parameters

pSrcDst

Pointer to the source and destination vector.

len

Number of elements in the vector.

value

Constant value to be assigned to NaN elements of the vector.

Description

This function replaces not-a-number (NaN) elements of the source vector with value, other vector elements remain unchanged:

pSrcDst[i] = (pSrcDst[i] == NAN) ? value : pSrcDst[i]

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when pSrcDst is NULL.

ippStsSizeErr

Indicates an error when len is less than, or equal to zero.
