% Create vandermonde matrix for points x and polynomials of order p % x is a list of N points of size [N,dim], % p is a list of polynomial orders of size [M, dim]. % the given mononomials are evaluated and the NxM matrix V is returned. function V = vandermonde(x, p) assert(size(x,2) == size(p,2), 'x and p must have the same number of columns') n = size(x,1); m = size(p,1); for i = 1:m V(:,i) = mononomial(x, p(i,:)); end assertSize(V,[n,m]); end
