Continuing with the random walk data: We will be bootstrap sampling the prior data to get estimates of what the next series of samples could look like. if (typeof(playerLoaded) === ‘undefined’)… 続きを読む >>
This week we do a code review of some random walk data, making a heatmap with adjoining histograms to better understand the distribution of data. It shows the implementation of visualizations… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
