Math Group:


mat = " a 2 dimensional matrix of numebers"

interp = ListInterpolation[mat];

Later in my program, I change the "numbers" in mat.  What happens to 

That is, does interp reflect the new "numbers."  Or, do I have to 
redefine interp each time after I make a change to mat.

I'm worried about the speed of my program.  If I indeed do have to 
redefine interp, doesn't this take time?  Is there a more elegant 
solution out there?
