PolyGFSetCoeffs

Defines the polynomial.

Syntax

IppStatus ippsPolyGFSetCoeffs_8u(const Ipp8u* pCoeff, int degree, IppsPoly_GF8u* pPoly);

Parameters

pCoeffs	Pointer to the array of values to be used as coefficients of the polynomial.
degree	The degree of the polynomial. The number of elements of the array pCoeffs to be used as polynomial coefficients is (degree+1).
pPoly	Pointer to the ippsPoly_GF8u context to be updated with the specified value of degree and the set of coefficients.

Description

This function is declared in the ippdi.h file. The function copies (degree+1) values from the array pointed by pCoeffs to the coefficients of the polynomial pPoly and assigns the degree value to the degree of the polynomial.

In Intel IPP, the lower index of an array corresponds to the lower power of the independent variable. For example, to define the polynomial p(x) = 2x⁵ + 17x² + 5x + 3, use the array {3, 5, 17, 0, 0, 2}.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr	Indicates an error condition if any of the specified pointers is NULL.
ippStsContextMatchErr	Indicates an error condition if the context pointed by pPoly is not valid.
ippStsBadArgErr	Indicates an error condition if the value of the parameter degree is less than 0 or greater than the highest possible value specified in the context.
