There are certain timeless questions about MATLAB. I was just asked about this and knew I had made a video about changing object properties in GUIDE.

When we design a program, the way we store our data will have an effect on how our code looks as we manipulate that data later. In this video we had the choice to store the coordinates of a robot… 続きを読む >>

When you vectorize code, you avoid looping through an array and instead do operations on the matrix level. This avoids for loops in MATLAB. The reason for vectorizing are often stylistic…. 続きを読む >>

A callback is a function that gets called when you perform certain actions. For instance, you might want something to happen when you click on a line in MATLAB, or when you move the mouse in MATLAB…. 続きを読む >>

If you push a button in a MATLAB UI and this starts a long calculation, what do you want to have happen if the user pushes the button a second time? Interuptable property and BusyAction property of… 続きを読む >>

This week we are making up some data and doing a couple of visualizations. We then modify the data to do a reality check on a simple algorithm. This allows us to gain confidence in our algorithm… 続きを読む >>

I have been using MATLAB tables lately. In doing that, MATLAB will store meta data with your numeric data. I was bringing data in from Excel files. Each column name will eventually become a… 続きを読む >>

I often say that one my greatest qualifications for troubleshooting MATLAB code is that I know I am not that clever, so I have to simplify things until I can understand them easily. It works really… 続きを読む >>

Recently, I needed to plot two different sets of time series data on the same axes, but they were at different scales. In this simplified example, I show how you can change the x-labels to display… 続きを読む >>

In this video we are sorting through some data making a different line for all the data points that match certain criteria. At some point in the algorithm none of the data meets the criteria. This… 続きを読む >>
