prtools svm on linux

the last few days I've been trying to get svm working with prtools. Prtools seems convenient, but I got an error that qld wasn't found and that it was using the matlab quadratic programming function instead. I found a forum where they have a download for the qld.c function. It was easy to compile with mex and it seems to be running much faster now. I don't know why they didn't include the .c file to begin with, but I figured it out anyway.... here's the link to the forum http://prsysdesign.net/index.php/forums/viewthread/22/
