This video covers the use of GRIDDATA, anonymous functions, and QUAD2D to integrate the volume under a set of randomly spaced data points. First an interpolation scheme must be put in place, then a… read more >>

This video will demonstrate how to implement a formula in MATLAB. In the video, we will make a function out of the formula. The function will take a scalar (single number) or a vector. We want to… read more >>

This short video covers the thought process of rewriting some code for clarity. The six lines of code are lengthened into twice that. The code is much more readable and maintainable. The problem… read more >>

The “Rules of the new game” puzzler was the most difficult one yet. Puzzlers are MATLAB programming challenges that I post from time to time. They lead to interesting discussions of… read more >>

I was playing a game by LabPixies on my iPhone. I spent more time thinking about programming an optimal solution than anything else while playing. I decided to give it a try in MATLAB. After… read more >>

The contour plot will choose the colors of the contour lines based on the level of the contour. However, if you want to do something more, like change the line width or line style, you will need to… read more >>

I was interested in visualizing isolines on a graph of BMI. This is a non-linear function of two variables. I thought the best way to visualize this would be with a contour plot. This video… read more >>

In this short video we will show how to bring text files into MATLAB and use the original file name as the variable name. Actually, the file name will be used as a field name in a… read more >>

This is the fourth in a series of videos that will go through the process of planing and implementation of a simple GUI. Realistically, I would not plan out a GUI this simple, but the idea is to… read more >>
