Greg's pick this week is MATLAB Dependency Injection by Matt McDonnell. Imagine you want to build an application that dresses you in the morning. What... read more >>

Jiro's pick this week is The X Collection by Yvan Lengwiler. My day job is a customer training engineer. I get to take people who have never used MATLAB or Simulink to the point where they feel... read more >>

Sean's pick this week is mcolon by Bruno Luong. As some of you may know, I spend an unhealthy amount of time on MATLAB Answers browsing through... read more >>

Sean's pick this week is WorkerObjWrapper by MathWorks' Parallel Computing Team. Background MATLAB's Parallel Computing Toolbox provides you with the the ability to open a pool of MATLAB... read more >>

Very often MATLAB users want to be able to process a set of files from a directory. In this video, I show how you can look through a directory seeking files of the form “data###.dat” and then returning the “###” as a number with any leading zeros removed. This makes… read more >>

We have MATLAB users come into The MathWorks to present their work in MATLAB from time to time. Recently there was an interesting presentation with some really great “Clutter classification” algorithms in a GUI. One of the questions that came out of that discussion was how to get rid of… read more >>

This week we will be looking at the MATLAB class system. This video does not cover the “why” of doing OOP (Object Oriented Programming) in MATLAB. It just covers a very simple example of doing OOP.
The ten minute video shows an implementation of Conway’s Game of Life in MATLAB with… read more >>

This is a puzzler without explanation. Brett got it in about five minutes, some of the other folks wandering near my office got it in just under 20.
The data to explore.

This week’s puzzler is significantly harder than others we have done in the past, I would be surprised (and delighted) to see an answer before I go home tonight…
The challenge is shown below.
Given a group of trees, find the rectangular bounding box in the x-y direction that holds… read more >>

Sometimes you want something to update in MATLAB on a regular schedule. Timer objects can do that for you. We first introduced this for test and measurement applications, but it has since been moved into base MATLAB.
In this simple example, we will create a timer object and have it fire… read more >>
