In the last video we interactively changed the colormap so that there was a clear break between negative, positive and NaN values. In this video, we change the range of data, so the colormap needs… 更多内容 >>

I was doing a visualization and needed to change to a custom colormap to get a better understanding of the data. This video shows how to interactively modify a colormap such that NaN values take on… 更多内容 >>

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… 更多内容 >>

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… 更多内容 >>

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… 更多内容 >>

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… 更多内容 >>

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… 更多内容 >>

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… 更多内容 >>
