LEGENDRE Associated Legendre Polynomial

Section: Mathematical Functions

Usage

Computes the associated Legendre function of degree n. 
  y = legendre(n,x)

where x is either a float or double array in range [-1,1], n is integer scalar. The output vector y is the same size (and type) as x.

Example

Here is a plot of the legendre function over the range [-1,1]. 
--> x = linspace(-1,1,30);
--> y = legendre(4,x);
--> plot(x,y); xlabel('x'); ylabel('legendre(4,x)');
which results in the following plot.
