I got a quick question today on how to make a diamond appear on an image in MATLAB. This is really an exercise in indexing and for loops in MATLAB. Let’s see how you can make an image in… 続きを読む >>

Sometimes the performance of MATLAB code can depend greatly on the algorithm or the specific functions called. In this example, we show how we use the profiler (and good knowledge of logical… 続きを読む >>

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 >>
