For fatal crash and burns like that, see the FAQ: http://matlab.wikia.com/wiki/FAQ#After_installation.2C_MATLAB_crashes_or_gives_an_error_message_when_I_try_to_run_MATLAB. - basically, call the Mathworks.

Are you using any third party executable files like DLLs? Or is it all just straight out-of-the-box MATLAB code? There could be many complicated reasons for such a crash and we aren't able to troubleshoot much, which is why the FAQ recommends you contact the Mathworks.
