I am John Kelly, the Administrator of MATLAB Central.  As part of the MATLAB Central 15^th Anniversary Celebration we thought it would be interesting to have a series of interviews with key contributors to MATLAB Central.  Naturally we thought 15 questions seemed appropriate.

Our first interview is with Chad Greene.… read more >>

You’re part of a long tradition.

Communities don’t blossom in one night. MATLAB’s rich community has been growing steadily for many years, and today I want to give you an idea of just how long. I bet it’s longer than you think!… read more >>

MATLAB Central launched 15 years ago, in the fall of 2001, and it’s been growing fast ever since. I’ve had a front row seat for the entire show, and it’s been great fun. I’m… read more >>

We did some web updates last night, and Cody emerged with a fresh coat of paint. As a result it’s more mobile-friendly. The tags for each problem are a little more prominent on the right side…. read more >>

Let’s say you’ve written some code that you think might worth adding to the File Exchange. But then you hesitate. Your Tiddlywinks Trajectory Simulator function (TiddleSim.m) is nifty…. read more >>

I think of the wise and generous John D’Errico as a computational philanthropist. After a long career as a numerical analyst at Kodak, he retired to what could have been complacent indifference… read more >>

Let me start with a graphical riddle. In what sense is the following equivalence true?

To learn the answer, read on!
I recently came across Nick Higham’s fun post on one-liners in MATLAB. That… read more >>

Collaboration on software can be a lot of fun, but it can also be hard to motivate.

For instance, you may be working on a project and you’d love some help, but you can’t get anyone else excited about your Interactive Polhode-Herpolhode Animator. Alternatively, you may be willing to help with somebody else’s project, but how do you find something that’s interesting to you and simultaneously needs and wants your help? Because if you’re going to spend time hacking code, you want to make sure somebody actually cares.… read more >>

I want to show you a trick for finding entertaining MATLAB code. Of course I will always recommend that you start looking on the File Exchange or on Sean and Jiro’s awesome Pick of the Week or… read more >>

Cody is a game that rewards you for calculating the same answer with less code. The very first Cody problem you encounter is called Times 2. It’s a starter problem, so it’s meant to be… read more >>
