Adding UICONTROLS to MATLAB without GUIDE for simple interactive figures 7

There are often small tweaks to functionality that you would like for a figure in MATLAB. This video shows how to add a button to a figure that will allow you to toggle the units of a y axes between… read more >>

Simple visualizations for a statics problem in MATLAB

A colleague was trying to draw some structures and do basic static analysis on them. He wanted to write a routine that would draw a pinned beam given the locations of the two pins. This can be done… read more >>

GUI building in MATLAB 8

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 >>

Indexing to make an image in MATLAB 1

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 >>

Example: Speed up MATLAB code by profiling

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 >>

Visualizing random walk data (3/3)

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 >>

Visualizing random walk data (2/3) 2

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 >>

Visualizing random walk data (1/3) 4

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 >>

Dynamically created colormaps

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 >>

Modifying a colormap interactively

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 >>
