Avoid loop in matrix operation [message #49226]

Hi everybody,
My question is very generic. How can I make operation on a matrix
whitout using loop ?
Here is an example, where I have, for example a topographic map
changing with time H(i,j,t), and I want to know the mean topography. I
did that and it works well:

FOR i=0,Nx-1 DO BEGIN
FOR j=0,Ny-1 DO BEGIN
H(i,j)=MEAN(H(i,j,*))
ENDFOR
ENDFOR

But I like one-line code. Is it possible to do the same thing in a more
efficient and compact way ?

I'm sure you have an answer for me !
thanks
Laurent
