Integrating to find the volume underneath a set of nonuniformly spaced data 13

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 >>

Basics: Implementing a formula in MATLAB 5

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 >>

Basics: Code review- the thought process in rewriting code for clarity 14

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 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 >>

Basics: Visualizing a function of two variables

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 >>

Advanced: loading files using their names for variable names 22

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 >>

Using HIST and BAR to customize your histograms 14

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… read more >>
