Ok, so before, I didn't see this message.
You're sort of changing things around here.
You started from ONE array with 200x200 elements and wanted to make something of 100x(40000) elements. This of course will never work.
What you really want is to make a 100x200x200 array from 100 arrays of 200x200. Correct?
But where do you get the 100 arrays of 200x200?
Try this:
finalArray = fltarr(100,200,200)
for i=0, 99 do begin
;generate the array
a = randomu(s,200,200)
;put it in the final array
finalArray[i,0,0] = reform(a,1,200,200)
endfor
Regards,
Helder
