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 >>

Today’s challenge is one where you need to figure out if two rectangles have a non-zero area of overlap.
The rectangles will be specified as follows:

Jiro's pick this week is NEWFCN by Frank González-Morphy.
We all have our own style of writing functions in MATLAB. I've adopted a convention that is similar to the "best practice"

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 was a fun little puzzle. I wonder how many people got to the first image, but did not continue to the real solution! Contents Load the data and... read more >>

This is a puzzler without explanation. Brett got it in about five minutes, some of the other folks wandering near my office got it in just under 20.

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 >>

Update: This solution was found faster than expected. I have replaced the original with a stronger solution that I was holding in reserve. Congrats to DanK for solving the original ( found here… 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 >>
