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 >>
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 >>
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 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 >>
