convex optimization problems in octave (trying to replace Matlab with Octave in university)

[Ioan Eugen Stan]

Hello,

I attend a class called Numerical Methods for Economic Systems that
requires some matlab programming knowledgs and I am trying to convince
the professor to recommend Octave instead of Matlab.
He asked me to make a presentation about Octave and how can you solve
a convex optimization problem using Octave (determine the optimal
volume of a tin can so as to use the least amount of material).

The problem is classic and seems simple. I have a lot of things to do
and I'm not that big of a fan of numerical methods so please give me
some references or links to some code so I can make my presentation.

I think Octave is much more suited for the job the professor wishes to
teach us and I do wish to see this change in my school, because not
all of the students can afford Matlab and pirating is bad.

Regards,

p.s. I am not on the list so please add me to C.C. field.
