Perhaps you might try:
Map[ f, mat, {2}]
It's the third "further examples" in the help for map.

Dear all,
how do I thread a function over all elements of a matrix?
This piece of code works, but I doubt its the way i am supposed to do
this
mat=Table[i+j,{i,0,2},{j,0,2}]
Map[Map[f[#]&,#]&,mat]
I tried
Map[f[#]&,mat,2]
Apply[f[#]&,mat,2]
Thread[f[mat]]
but they give weird results.
Cheers
Ben
