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 >>

This video is about how to debug in MATLAB. This video shows an error that occurs only now and then when using random inputs. A technique for capturing the random inputs, using dBSTOP IF ERROR, the… read more >>

This video assumes you have watched this video that outlines a simple encryption algorithm. The video shows a quick code review of my algorithm. Warning: this video is part of a longer series, I… read more >>

I have liked cryptography since I was sending Caesar cipher messages to my fellow 6th graders. The essence of that was to ‘add’ a value to each letter of your message. With Caesar, it… read more >>

This video shows how to put an individual text label on each of a series of points. This video also shows a simple technique for understanding lines of code where there are many functions… read more >>
