This week’s puzzler is significantly harder than others we have done in the past, I would be surprised (and delighted) to see an answer before I go home tonight… The challenge is shown… read more >>
It is no secret that I like teaching MATLAB through videos. I use Camtasia to make and edit my videos, I am very happy using it. If you want to make MATLAB videos too, you can use Jing, by the… read more >>
Here is a new MATLAB Puzzler. Given two vectors representing the X and Y coordinates of some points, find the two closest points in Cartesian space. n = 10; x = rand(1,n); y = rand(1,n); … read more >>
This week we will take a look at how you can capture the mouse movement through callbacks. As the mouse moves, we will update the xdata of a line so that you are moving the line with the mouse. if… 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 >>
When MATLAB throws an error, if you are in a function, you will end up at the base workspace and lose access to the variables as they were in the function when the error was thrown. This makes it… read more >>
This short video covers the difference between a “structure of arrays” and an “array of structures”. if (typeof(playerLoaded) === ‘undefined’) {var playerLoaded =… read more >>
There are three inputs to every automatically generated callback from GUIDE: function edit1_Callback(hObject, eventdata, handles) A common question that I am asked is “What is the handles… read more >>
