Is there a function to tell whether the installed matlab is 32 bit or 64 bit?

Is there a MATLAB function to tell whether the installed MATLAB is 32 bit or 64 bit? The National Instruments NI488 package needs a different .dll loaded, depending on which version of MATLAB is installed.

mexext returns differently for the two.

Thanks! That's a better solution than: [x,y]=computer;log2(y), which returns 31 for a 32 bit install and 48 for a 64 bit install
