I was trying to do
mex -setup
but it didn't work and gave me:
Error using mex
No supported compiler or SDK was found. For options, visit
http://www.mathworks.com/support/compilers/R2015b/maci64.html.
I tried going to that link but the link just didn't exist. Does anyone have some advice on how to run that command?
(the reason I was running this was because I wanted to use matconvnet http://www.vlfeat.org/matconvnet/quick/ quick start example)

Brando - the above link brings you to the "System Requirements and Supported Compilers" page. From there you need to select the "Supported Compilers" link, http://www.mathworks.com/support/sysreq/files/SystemRequirements-Release2015b_SupportedCompilers.pdf. Navigate to page seven - do you have Xcode installed? Because you will need it for MEX file compilation.
Once you have installed a compiler, then try the above command again (to set up MEX). You can also try
mex -setup -v
which provides more (verbose) information on the setup.

The trick is to not include the final period in the link.
http://www.mathworks.com/support/compilers/R2015b/maci64.html. -- fails because of the trailing period
http://www.mathworks.com/support/compilers/R2015b/maci64.html -- works
