Hi,
I am trying to run the Deep Learning Framework on Matlab and the instructions are unfortunately, confusing for a newbie like me.
I am supposed to "Install MATLAB, and make sure that its mex is in your $PATH"
1) What is mex and how do i make sure that 'its' mex is in my $PATH ? I have done a bit of searching on google and it turns out that mex allows Matlab to read code written in C/C++ ? I have also tried to use the cmd line in matlab to setup mex but it says "No supported compiler or SDK was found."
2) Do I need to install visual studio for this ?

It has been quite a number of years since any Visual Studio Express was supported. If you look at the list at http://www.mathworks.com/support/compilers/R2014a/win64 you will see that it specifically lists the Professional versions, not the Express versions.
Depending on which operating system you are using, you might be able to use the SDK 7.1 . However, if you are using Windows 10, you are probably not going to be able to get any compiler to work with your R2014a MATLAB, unless perhaps you can get one of the commercial Intel compilers to work.

Here you said you are using Windows 10. In your duplicate question (which I have moved to above) you say you are using Windows 7. Which is it? It makes a big difference in compiler support!

If you are using SDK 7.1, then just install Microsoft's SDK 7.1, and then at the MATLAB command line give the command
mex -setup
