Note: the way Mex setup works has changed in R2014a and newer. This is for older version of Matlab R2013 and older

Ubuntu 14.04 comes with GCC 4.8, but Matlab R2013a gives warnings about needing GCC 4.4 if using MEX features.

(1) Packages to install (synaptic or apt-get)

gcc-4.4
g++-4.4


(2) in Matlab, type  mex -setup and press 1 to copy the mexopts.sh to your ~/.matlab/R2013a/mexopts.sh

(3) sudo chmod 644 ~/.matlab/R2013a/mexopts.sh
(allows you to edit this file)

(3) gedit mexopts.sh
and change:

CC='gcc-4.4'
CXX='g++-4.4'


Also to save yourself grief when you’re using a modern C++ syntax file (especially if you get errors like
error: expected expression before ‘/’ token
)
then make this additional changes:

#CFLAGS='-ansi -D_GNU_SOURCE'
CFLAGS='-std=c99 -D_GNU_SOURCE'


(4) Save/exit gedit and restart Matlab. You should now be able to use MEX in Matlab R2013a under Ubuntu 14.04.
