| 1 % Create vandermonde matrix for points x and polynomials of order p | |
| 2 % x is a list of N points of size [N,dim], | |
| 3 % p is a list of polynomial orders of size [M, dim]. | |
| 4 % the given mononomials are evaluated and the NxM matrix V is returned. | |
| 5 function V = vandermonde(x, p) | |
| 6 assert(size(x,2) == size(p,2), 'x and p must have the same number of columns') | |
