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. -- I don't reply to email anymore. If you have a question about my questionable FEX submissions, leave a comment on the FEX page and I'll get the notification. Alternatively, ask a question on the forum and @DGM me so I'll get notified.

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.
