Polynomial() [2/5]

template<typename FloatingType>

dsp::Polynomial< FloatingType >::Polynomial	(	const FloatingType *	coefficients,
		int	numCoefficients )

Creates a new polynomial with given coefficients.

Parameters

numCoefficients	The number of coefficients stored in coefficients. This is also the order of the returned polynomial.
coefficients	The coefficients which will be used by the newly created polynomial. The Polynomial class will keep a private copy of the coefficients.
