SHAREDMATRIX Allows any Matlab object to be shared between Matlab sessions (w/o using file I/O).

% --- Possibly useful notes. ------------------------------------------------


% --- Note 1 ---


% If you have trouble compiling in Matlab (GLIB error) try prefixing the matlab
% command with a LD_PRELOAD, ie,
% $ LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 matlab


% --- Note 2 ---

% http://morganbye.net/blog/2011/05/matlab-ubuntu-1104
% 
% MATLAB with Ubuntu 11.04
% 
% Under the new Ubuntu 11.04 (Natty Narwhal), when you try and run MATLAB
% you'll get the following error
% 
%     /matlab/bin/util/oscheck.sh: 605: /lib64/libc.so.6: not found
% 
% To resolve this problem, go to a terminal window (Alt + F2 from anywhere) and
% type:
% 
% For 64 bit:
%     sudo ln -s /lib64/x86_64-linux-gnu/libc-2.13.so /lib64/libc.so.6
% 
% For 32 bit:
%     sudo ln -s /lib/i386-linux-gnu/libc-2.13.so /lib/libc.so.6
% 
% This should restore the missing library that was uninstalled during the
% Ubuntu update process.
