I think I’ve found a mistake in the MATLAB Documentation and I’d like to report it!

http://www.mathworks.com/help/matlab/ref/find.html?searchHighlight=find#budqvnh-1

k = find(X,n,direction), where direction is 'last', finds the last n nonzero elements in X. The default for direction is 'first', which finds the first n nonzero elements.

This function finds the indices but not elements. So the correct definition is:

k = find(X,n,direction), where direction is 'last', finds the last n indices corresponding to the nonzero elements in X. The default for direction is 'first', which finds the first n indices corresponding to the nonzero elements.

That's probably a more accurate description. You can click "No" on the button at the bottom of the documentation page that says "Was this topic helpful". I know for a fact that there is a live human that looks over every one of those that people report.
