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 >>

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 >>

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… 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 >>

Cody is one of my favorite ways of learning MATLAB. I have recently created a problem in Cody where you are to solve addition problems of this puzzle style: W A I T + A L L … read more >>

Knowing what visualizations of your data are useful is half the challenge. We recently added a plot type gallery to our website. It allows you to see many different MATLAB graphics at once. Find… read more >>
