Try to use the above statement, a bit altered:

        (setenv "PATH" (concat "/Applications/MATLAB_R2012a.app/bin" ":" 
(getenv "PATH")))

(I presume the "matlab" file in the "/Applications/MATLAB_R2012a.app/bin" 
directory is already the executable, so it may not appear in PATH because then 
the matlab executable would be searched for in the not existing *directory* 
/Applications/MATLAB_R2012a.app/bin/matlab), maybe plus the following one:

        (setq exec-path (split-string (getenv "PATH") path-separator))

The variable exec-path is responsible for supplying sub-processes in GNU Emacs 
with a search path for executables. You can also customise this variable, but 
would need to edit it when it changes when Matlab gets updated – just as with 
the "(setenv "PATH" ...)" statement.
