In some code there is an enumerated set of choices. People will use a switch case statement to check for all but one choice and then catch that last one in the ‘otherwise’ block of their… 続きを読む >>
There are situations where you want MATLAB to remember the value of a variable from one call of a function to another call of that function. We show to use a persistent value to accomplish this. … 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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 >>
