Using mex does not work but the link it directs me doesn't exist

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
