MATLAB: How to find out the full path for a directory

MATLAB

I have the name of a directory, but I would like to find out its full path. How can I do that?

You can use the "what" command. Please refer to the documentation here: <http://www.mathworks.com/help/matlab/ref/what.html>

>> s = what('myDir');
>> s.path
ans =
C:\path\to\myDir

[filename, path] = uigetfile('Pick a file');
fullname = fullfile(path, filename);
TheImage = imread(fullname);   %use the file as appropriate

uigetfile allows the user to navigate between directories and will return the name of the directory used.

You can use the "yyaxis" and "ylim" commands to set the y-limit for both axes:

>> figure

>> yyaxis left

>> plot(1:10);

>> yyaxis right

>> plot(2:2:20);

>> f = gcf;

>> yyaxis left

>> ylim(f.Children, [0 5]);

>> yyaxis right

>> ylim(f.Children, [5 10]);
