Example data sets in Matlab

Question

There are several example data sets in Matlab, for example wind and mri. If you execute the command load wind you will load the data in the data set wind. Some are included in toolboxes and some appear to be included in standard Matlab. These example data sets are valuable as test data when developing algorithms.

Where can one find a list of all such data sets included in Matlab?

Answer 1

You can enter demo in matlab to get a list. The wind table is part of Example — Stream Line Plots of Vector Data, etc.

For the tables on your computer, have a look at:

C:\Program Files\MATLAB\R2007b\toolbox\matlab\demos

Answer 2

The example data is located in .mat files in ../toolbox/matlab/demos. The following data is available in MATLAB 2014a:

% in matlab run:
> H=what('demos')
> display(H.mat)

You can also use your favorite Linux console:

/usr/local/MATLAB/R2014a/toolbox/matlab/demos$ ls *.mat -1 | sed -e "s/.mat//g"
