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… 続きを読む >>

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… 続きを読む >>

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… 続きを読む >>

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… 続きを読む >>

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… 続きを読む >>

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… 続きを読む >>

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… 続きを読む >>

I commonly am asked how to learn MATLAB. Here are common questions and answers. What MATLAB books or MATLAB tutorials should I use? I am, of course biased on this. I think this blog is a… 続きを読む >>
