Support Vector Machines

For our Applied Topics in Mathematics class we had to code up some basic versions of support vector machines.  One of my classmates and I coded the following 3:  A hard margin, one-margin maximal weight SVM and 2 soft-margin maximal margin SVMs (one-norm & two-norm versions).  The next few posts will be the MATLAB code of those machines.  Feel free to comment on them and offer any suggestions where appropriate.
