This post is a continuation of the last video where we built a simple GUI in MATLAB. This continues by showing how to run initiation code for a MATLAB GUI and explains what the handles structure… read more >>

As we approach video number three hundred on this blog, I thought it was time to remake the original video that got this all started. I still refer people to it on a weekly basis. This shows you… read more >>

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… read more >>

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… read more >>

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’)… read more >>

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… read more >>

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 >>
