LegNorm {MissMech}

Evaluating Legendre's Polynomials of Degree 1, 2, 3, or 4

Description

This function evaluates the values of Legendre polynomials of degrees 1 to 4 on [0,1] at a value(s) x.

Usage

LegNorm(x)

Arguments

x

A scaler or vector of values at which the Legendre's ploynomials are to be evaluated.

Value

The returned list has the following elements:

p1

p1 is value(s) of the Legendre's polynomial of degree 1 at x

p2

p2 is value(s) of the Legendre's polynomial of degree 2 at x

p3

p3 is value(s) of the Legendre's polynomial of degree 3 at x

p4

p4 is value(s) of the Legendre's polynomial of degree 4 at x

Note

Legendre's polynomias on [0,1] are calculated.
