I work in technical support, so very often I get strange requests. Really strange. My first question is “Why do you want to do that?” The reason I ask this is very often new… read more >>

I very much advocate “No premature optimization” because until the code is running and pushed through the profiler, it is difficult to know where the bottlenecks of speed are. In this… read more >>

In this MATLAB video we show how you can manipulate the clim property of an axis to determine the points that an image will saturate the colormap. This is often a better choice than making a strange… read more >>

This video shows the implementation of the plan for how to find the closest point on a surface to a given point. This is a numerical approximation that avoids the inevitable complexities of solving… read more >>

I had a well formed question from an advanced MATLAB user recently. He wanted to have an output come back from a GUI. There is an example of this with the modal dialog example in GUIDE. However, it… read more >>

This week, I am going to cover a technique that I used to speed up a data mining application that had a search through enumerated strings looking for all the matches. Using this technique of… read more >>

This short video makes a 2d histogram as an alternative to plotting data points and visually estimating where the most data is. if (typeof(playerLoaded) === ‘undefined’) {var playerLoaded =… read more >>

This short video uses the Mapping Toolbox to load in the state boundaries in a given area and display them on a special map axis. Random points are also generated and filtered based on their… read more >>

A MATLAB user recently asked how we could make a visualization similar to this one. I was a little surprised that we were able to do the visualization, with interactivity in less that 15… read more >>

Here is the wrap up of the MATLAB programming contest that we just ran. if (typeof(playerLoaded) === ‘undefined’) {var playerLoaded = false;}(function isVideojsDefined() {if (typeof(videojs) !==… read more >>
