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 >>

This video shows how to fix common errors in MATLAB when indexing into a vector or matrix in a for loop. if (typeof(playerLoaded) === ‘undefined’) {var playerLoaded = false;}(function… read more >>

This short video shows how to change the tick labels on a plot. You might want to do this for bar plots, or just a regular plot that you want to customize. if (typeof(playerLoaded) ===… read more >>

Lots of MATLAB functions want strings as inputs. Very often MATLAB users want to use the value of a variable in that string. This video tutorial shows how to do that. if (typeof(playerLoaded)… read more >>
