10Log10

Computes the decimal logarithm of each element of a vector and multiplies it by 10.

Syntax

IppStatus ipps10Log10_32s_Sfs(const Ipp32s* pSrc, Ipp32s* pDst, int len, int scaleFactor);

IppStatus ipps10Log10_32s_ISfs(Ipp32s* pSrcDst, int len, int scaleFactor);

Parameters

pSrc	Pointer to 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	Refer to Integer Scaling in Chapter 2.

Description

The function ipps10Log10 is declared in the ipps.h file. This function computes the decimal logarithm of each element of the vector pSrc, multiplies it by 10, and stores the result in pDstas given by

pDst[n] = 10*log₁₀(pSrc[n]).

The in-place flavor of ipps10Log10 computes the decimal logarithm of each element of the vector pSrcDst, multiplies it by 10, and stores the result in pSrcDst as given by

pSrcDst[n] = 10*log₁₀(pSrcDst[n]).

If the function ipps10Log10 encounters a zero or negative value in the input, it returns a warning status and continues execution with the corresponding result value (see Appendix A "Handling of Special Cases" for more information).

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.
ippStsLnZeroArg	Indicates a warning for zero-valued input vector elements.
ippStsLnNegArg	Indicates a warning for negative input vector elements.
