Very often MATLAB users want to be able to process a set of files from a directory. In this video, I show how you can look through a directory seeking files of the form “data###.dat” and… read more >>

We have MATLAB users come into The MathWorks to present their work in MATLAB from time to time. Recently there was an interesting presentation with some really great “Clutter… read more >>

Often if you make a surface plot with SURF for a large dataset, it will appear all black because MATLAB is trying to draw all the edge lines. You can stop these lines from obscuring your data by… read more >>

People often make their own GUIs in GUIDE and they have a data visualization. When you embed an axis in your own GUI rather than using a figure window, you lose the built in toolbar that has zoom,… read more >>

This week we will be looking at the MATLAB class system. This video does not cover the “why” of doing OOP (Object Oriented Programming) in MATLAB. It just covers a very simple example of… read more >>

This short video shows how you can take a sparsely sampled sine wave and use interp1 to interpolate the missing data points. Different interpolations such as linear, spline and nearest are all shown…. read more >>

Sometimes in MATLAB you are going to want to store different data types together in one construct rather than try and keep track of different variables. Structures work for this, but sometimes it is… read more >>

Last time, I showed how to add the newly documented UITABLE to a GUI. [click here] There were a few questions [click here] about how to access the data in the UITABLE from the callback of another… read more >>

MATLAB GUI developers often want to have a mini-spreadsheet in their GUI. This can be done with a new widget added to the set of controls available in GUIDE. Now with UITABLE you can add that… read more >>

Sometimes you want something to update in MATLAB on a regular schedule. Timer objects can do that for you. We first introduced this for test and measurement applications, but it has since been moved… read more >>
