Compute Chebyshev L2 norm
y=chebyshev_norm(n)
a 1-by-1 matrix of doubles, integer value, n>=0.
a matrix of doubles, the norm
Compute the integral
If n=0,
If n>0,
// Check int Tn(x)^2 w(x) dx function y=sqTw(x, n) w = chebyshev_weight(x) P = chebyshev_eval(x,n) y = P^2 * w endfunction for n = 1:5 [v,err] = intg(-1,1,list(sqTw, n)); disp([n, chebyshev_norm(n), v]) end
