Legendre polynomial Pm(x)

Work of this function was checked with Matlab v. 7.0.4.365 (R14) SP2.
a) function works, however it gives a warning "Warning: Could not find an exact (case-sensitive) match for 'legendrep'... a case-insensitive match and will be used instead." After renaming mfile from 'Legendrep.m' to 'legendrep.m' warning disappeared.
b) I?m not sure, how polyval can be used instead of 'legendrep.m' to generate Legendre polynomial, so this comment is ignored

Found a bug for m>=13.
In the loop, the variable ii should be changed to (ii+10) when it not is used as an index for pp.

        N=ii+10;
        p_ii=[num2str(1/(N)) ' * (' num2str(2*N-1) ' * ' x '.*(' ...
        deblank(pp(ii-1,:)) ')-' num2str(N-1) '*(' deblank(pp(ii-2,:)) '))'];
