The changes that were suggested last week have been implemented. This shows how some small changes can really improve your code, making it more maintainable and expandable. It is good to be able to… read more >>

A close friend of mine is just learning MATLAB. She needs to process a bunch of text files, and was able to write some code that will accomplish that. She came to me looking to bring her code to… read more >>

I like it when I find new productivity tips in the MATLAB environment. The new MATLAB Toolstrip shows keyboard shortcuts for all toolstrip items when you press the Alt-key, which reminded me that we… read more >>

Testing your code is important to make sure that it works correctly and continues to work correctly as you modify it. The more long lived the code, the more important testing becomes. I… read more >>

I think a lot about how to best teach MATLAB. It took me 18 years to learn what I know about MATLAB, I keep hoping I can teach all of it in a three day class. So far, it has never worked! The… read more >>

This is the final video in the cryptography series. In this we look at the final data that comes out of the random number generator. We are concerned to see that not every combination of random… read more >>

This is a quick technique that came out of the series we have been doing about the cryptography algorithm. If you have NaN (“Not A Number”) in your data, MATLAB will ignore them in a… read more >>

Today we will look further at the cypher algorithm, specifically the randomness of this algorithm. There are two different distributions to look at: distribution of single numbers (1,2,3,4) and the… read more >>

This video is more philosophical than about MATLAB syntax. When trying to understand the cycles that occur in the output of a pseudo random number generator, I first approached the problem in… read more >>

This next video shows how to think about the results from the profiler to speed up your MATLAB code. We do not spend much time on the actual optimization, but more on finding bottlenecks and… read more >>
