to speed up 'for' loop

hello,
i have a loop with the following format:
for n = 1:length(x)
if ....
.....
elseif ....
.......
end
end
I suspect that it takes too long and my program is stuck. the length of 'x' currently 1200 cells and it might vary. How can I speed this up?
thanks,

Processing 1200 items in an array would normally take too little time to measure meaningfully, unless the processing for each one takes a long time (in which case that is the problem rather than the for loop.)
I suggest you use the profiler to measure the performance. You could temporarily change the upper bound to something smaller than length(x)
You may wish to consider using waitbar()
