%
% Usage
%
% The polyval routine has the following syntax
%
% y = polyval(p,x)
%
% where p is a vector of polynomial coefficients,
% in decreasing degree (as generated by polyfit, for example).
% If x is a matrix, the polynomial is evaluated in the matrix
% sense (in which case x must be square).

function y = polyval(p,x)
y = p(1);
n = prod(size(p));
for i = 2:n
y = y.*x + p(i);
