In this video we start with some data from a random process. Each piece of data represents a small time period and change in value. Think of it as something like a stock ticker, very noisy with a… read more >>
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… read more >>
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… read more >>
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… read more >>
A close friend of mine is just learning MATLAB. She needs to process a bunch of text files, and was able to write some code that will accomplish that. She came to me looking to bring her code to… read more >>
I like it when I find new productivity tips in the MATLAB environment. The new MATLAB Toolstrip shows keyboard shortcuts for all toolstrip items when you press the Alt-key, which reminded me that we… read more >>
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 >>
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 >>
