Every six month we release a new version of MATLAB. This 2012B Release is kind of a big deal. There is a major change in the desktop that should increase the discoverability of features in MATLAB. … 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 >>

All the geeks know that Curiosity has landed on Mars. I am not sure of the extent of the use of MATLAB/Simulink on this particular project, but I know that JPL is a “major user” of… 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 video furthers our analysis of the solitaire cipher, which is really just a pseudo random number generator. In this video, we estimate the cycle time of our random number generator to determine… 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 >>
