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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
I recently had a question come in via e-mail where this MATLAB user wanted to be able to change the look of her histogram. The key to this problem was using HIST to generate the binning data and… 続きを読む >>
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… 続きを読む >>
