It is easier to solve a problem than to guess, what the problem is.

Hi, I'm nobody.
I don't belong here, but I have nothing better to do.
Matlab used to be part of my work.
Now it's part of my hobbies.
That's pretty sad, really.

Alan Weiss

I write documentation for MATLAB mathematical toolboxes, primarily optimization. I have also written documentation for PDE, statistics, symbolic math, and econometrics.

My pre-MathWorks job was with Bell Labs, primarily in mathematical models of data traffic, with a strong interest in parallel computation and in rare events (large deviations).

I do not provide private consulting. If you have a question, please ask on a public forum such as MATLAB Answers.
