How to calculate z=f(x,y) with loops [message #3151 is a reply to message #3054]

I need to calculate the value of z=f(x,y) .
Z is a 2D array (fltarr(n,n)).
X and Y are the X and Y indices of this array.

I'd like to calculate :

for y=0,n-1 do begin
for x=0,n-1 do begin
z(x,y)=...a function of X and Y (the function can be
of any kind)
endfor
endfor

But I'would like to do it without (or with only one ) for loops
for performance consideration.

Has somebody an idea ??
