A for loop is used to construct a simple matrix with an underlying pattern. Pre-allocation is addressed in the second half of the video. if (typeof(playerLoaded) === ‘undefined’) {var… read more >>

Transparency is a nice feature to make your visualizations look better and it also allows you to show data more clearly (pun not intended, but appreciated after the fact). It means that your data… read more >>

The use of whitespace can make your code more pleasant to read. This is not just a nicety, it actually makes it easier to see the structure of your code and makes it more clear where code breaks the… read more >>

I almost never use Simulink, so I never saw this function before (requires Simulink). Try this at the command line: a = 1; b = 2.5; c = ‘A string’; d = {a, b,… read more >>

Ever try to delete some values in a vector by looping through from beginning to end? I have, and failed because the indexing got confused as the vector changed. Here is one solution to that class… read more >>

I just worked on a case that typifies a situation I see in MATLAB fairly often. Unexpected results are not necessarily wrong results. I am a big fan of the “sanity check”, where if… read more >>

Sometimes, when you are given a piece of code, it works well and you want to learn from it. Reading through the code is not always that helpful if done all at once. It is too much to process. … read more >>

This MATLAB video tutorial shows you how to reverse the direction of an aixs or to change an axis to log scale. if (typeof(playerLoaded) === ‘undefined’) {var playerLoaded = false;}(function… read more >>

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 >>
