Removing if then else loop for efficiency [message #69309]

Hello,

apologies for my newb-ness, but I was hoping I could get some help
with increasing the efficiency of the following program:

At the moment it is like this

for i=0, N-1 do begin
for j=0, N-1 do begin
if i ne j then begin
;stuff
endif else begin
;more stuff
endif
endfor
endfor

It's way too slow at the moment, but I gather I can remove one of the
for loops and the if then else loop but I have no idea how!

Any help would be much appreciated and I can post the full program too
if it helps. FTR it's the RHS of a Hamiltonian.

Thanks again
