lobatto_polynomial, a MATLAB code which evaluates the completed Lobatto polynomial and associated functions.
The completed Lobatto polynomial Lo(n,x) can be defined by:
Lo(n,x) = n * ( P(n-1,x) - x * P(n,x) )where n is a positive integer called the order, x is a real value between -1 and +1, and P(n,x) is the Legendre polynomial.
The completed Lobatto polynomial Lo(n,x) has degree n+1, and is zero at x = -1 and x = +1.
