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… 続きを読む >>
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,… 続きを読む >>
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…. 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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); … 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
This short video covers the difference between a “structure of arrays” and an “array of structures”. if (typeof(playerLoaded) === ‘undefined’) {var playerLoaded =… 続きを読む >>
