[Aces-support] Matlab Memory Limits

[Ryan Abernathey]

This is not a real solution, but Matt Mazloff suggested I modify the  
original interp3 function to convert its internal variables to single  
precision. This was able to reduce memory usage enough for the script  
to work.

The larger question of Matlab's inherent memory limitations still  
stands...
