MATLAB, but no quadprog
I have MATLAB, but because I do not have the Optimization Toolbox, I do not have quadprog(). What are my options for getting the SVM problems solved?
Here are the options as I see them:
These are listed in roughly my order that I think they might work for me. Any thoughts or other options are welcome. How badly off will I be for the last couple assignments, or the final, if I cannot get any quadratic programming to work?

Re: MATLAB, but no quadprog
I'd suggest the third one. Download and use Octave. The installation is fairly painless, and I believe qp() is in the standard distribution. The only differences will be that some functions behave slightly differently, but the basic code is identical. You should be up and running quickly.
For help, you can either use "help fcnname" within Octave or refer to www.gnu.org/software/octave/doc/interpreter/ which is fairly easy to navigate. If you do install Octave, do check out my posts in the Quadratic Programming thread here about how to get qp() to work for this problem.

Re: MATLAB, but no quadprog
Some googling has turned up another option. I found this page, which has some routines that seem to be working:

Re: MATLAB, but no quadprog
Another option is to use cvx from Stanford (Boyd)

Re: MATLAB, but no quadprog
I am lucky to have the matlab optimization toolbox. I would advise against using cvx for this homework for anyone not familiar with it already, vs say using qp of Octave, because it requires its own learning curve.

This paper is clearly written and has an SVM algorithm presented in great detail and it explains how to incorporate other kernels into the routine. http://www.csie.ntu.edu.tw/~cjlin/pa...uadworkset.pdf I've got it running in C#. It didn't take long to code  most of the development time has been in testing. Now I actually understand what was derived in that lecture!
