If you have a UItable in a UI made in GUIDE, you might want to change that data in a callback. For instance, you might want to change the values or increase the size of the dataset. This short… 続きを読む >>
I recently wanted a colormap that was distinctive. I wanted the zero values to be one color while the negative and positive values were different shades. This video shows how to do this… 続きを読む >>
Knowing how to use callbacks in MATLAB allows you to customize your graphics and make them more interactive. This short video shows you how to highlight a line in MATLAB by clicking on it. if… 続きを読む >>
The profiler is very important when you want to speed up your code. It is nearly impossible to know where the bottleneck will be in your code until it is written and tested. Often times there are… 続きを読む >>
Do you need to develop an algorithm in MATLAB? Do you have tests in MATLAB that would tell you if the algorithm were working correctly? If you do, you might not need to actually write the MATLAB… 続きを読む >>
This video builds on the last one. A quick monte carlo test is built to see if the Luhn Algorithm really will detect transpositions. The testing indicates that only one pair of numbers transposing… 続きを読む >>
The Luhn algorithm is a fast checksum that allows you to know if an entered series of numbers has any of the repeated digits or transpositions that are common when typing numbers in. By having a… 続きを読む >>
Recently, a MATLAB user asked me how to build a UI which lets the user display any image in a directory by selecting the name of the image from a pop-up menu. This uses a few concepts like the DIR… 続きを読む >>
It is often easier to acquire or generate data than it is to understand the data. In this video, we explore different options for visualizing data to gain better insight to solve a problem…. 続きを読む >>
Many times we use difficult syntax in MATLAB because we do not know there is a better way and do not know to look for a better way. A recently saw some MATLAB code that could have been a lot… 続きを読む >>
