function y=evalfit(f,x)
%EVALFIT  Evaluate a fit
%   Y = EVALFIT(F,X) evaluates the fit F for the values X.  F is a fit
%   structure, as obtained by EZFIT, SHOWFIT or SELECTFIT. Y is a vector
%   of the same length as X, with Y(i) = F(X(i)).
%
%   Example:
%     plotsample('power');
%     f = ezfit('power; log');
%     x = logspace(1,3,1000);
%     hold on; plot(x,evalfit(f,x),'r-'); hold off;
%
%   See also EZFIT, SHOWFIT, FITPARAM.
