%> The file <legexp.m> gives a demo of the Legendre polynomials and 
%> associated Legendre functions. 
%> It also calculates expansions of functions in such a ON basis.
%> The definition of the Legendre polynomials can be found in most 
%> textbooks on quantum mechanics or angular momentum.  
%> Here we use the files <legpol.m> and <legfun.m> for rapid calculation
%> of matrices of function values. 
%> MATLAB also has a standard algorithm for the Legendre functions, 
%> which includes the polynomials as a special case. 
%> Notation P(M,L), L >= M >= 0 integers. 
%> M = 0 gives the Legendre polynomials.
