PolynomialBasis Class

Represents a FunctionBasis for the polynomials up to a specified degree.

[SerializableAttribute]
public class PolynomialBasis : FunctionBasis
Inheritance
Object  →  FunctionBasis  →  PolynomialBasis

Remarks

Use a PolynomialBasis object to represent a basis for the polynomials. Only in rare cases will it be necessary to construct a PolynomialBasis, as most functionality is available through the Polynomial class.

The basis functions of a PolynomialBasis are the monomials of degree 0 up to and including the specified degree.

The Chebyshev polynomials form an alternate basis for the polynomials and have many desirable numerical properties.

Constructors

PolynomialBasis Constructs a new GeneralFunctionBasis from an array of function of one variable delegates.

Properties

Item Gets an element of the collection as a function of one variable.
