When I come up with examples for functions that I write, the first several lines of my example files are often spent creating fake data. Example data like load train are quite helpful because they are built into Matlab, but I have not been able to find a clear list of what example data are available, and on what Matlab releases.

For my current task, I'd like to find a chart of example data associated with the Mapping Toolbox. Does this list exist somewhere?

I'm not sure that such a list for each toolbox exists. I noticed that the Statistics Toolbox mentioned some of the data sets that it includes ( http://www.mathworks.com/help/stats/_bq9uxn4.html) but I couldn't see anything for the Mapping Toolbox. You may have to do what Jason suggests below.

在 MATLAB Online 中打开

This will work:

pathFolderList = strsplit(path(),';');
matFilesOnPath = cell(size(pathFolderList));
matFileCount = 0;
for iFolder=1:length(pathFolderList)
  matFilesOnPath{iFolder} = ls([pathFolderList{iFolder} filesep '*.mat']);
  matFileCount = matFileCount + size(matFilesOnPath{iFolder},1);
end

I had 1,025 mat files on my path.

Bare in mind that you may have toolboxes other will not. If you stick to the folders contained as part of the core MATLAB functionality, you should be able to find data that everyone has if the versions are the same.
