EigenValuesGetBufSize

Computes the work buffer size for the functions EigenValues.

Syntax

IppStatus ippmEigenValuesGetBufSize_32f (int widthHeight, int* pSizeBytes);

IppStatus ippmEigenValuesGetBufSize_64f (int widthHeight, int* pSizeBytes);

Parameters

widthHeight

Size of the square matrix.

pSizeBytes

Pointer to the work buffer size value in bytes.

Description

The function ippmEigenValuesGetBufSize is declared in the ippm.h file.

This function computes the size in bytes of the work buffer that is required for the functions EigenValues and stores the result at the address of pSizeBytes. To compute the size of the buffer, you must specify the size (widthHeight) of the square matrix that you are going to compute eigenvalues for.

Return Values

ippStsOk

Indicates no error.

ippStsNullPtrErr

Indicates an error when the input pointer is NULL.

ippStsSizeErr

Indicates an error when the input size parameter is less or equal to 0.
