Why bother?
feeds = [0.1 0.2 0.3];
docs = [0.2 0.3 0.4];
rpms = [500 1250 2000];
[FEED, DEPTH_OF_CUT, RPM] = ndgrid(feeds, docs, rpms);
Tool_wear = 0.0076390 + 0.000024 * FEED + 0.001581 * RPM + 0.000422 * DEPTH_OF_CUT + 0.000389 * FEED .* FEED + 0.000663 * RPM .* RPM - 0.000849 * FEED .* RPM - 0.000749 * FEED .* DEPTH_OF_CUT + 0.000704 * RPM .* DEPTH_OF_CUT;
[minwear, idx] = min(Tool_wear(:));
fprintf('Minimum wear %g at Feed %g DOC %g RPM %g\n', minwear, FEED(idx), DEPTH_OF_CUT(idx), RPM(idx));

I have also got somewhat similar type of prob in which i have to minimise surface roughness on the basis of certain parameters. If anyone has pso program for it plz mail me at neerajbhanot.iitd@gmail.com
Thanks
