well, I don't see the point of using 3 where functions while they just
do exactly the same thing here. basically esc1=esc2=esc3, so you only
need 1 where() per loop. i guess shift function should work faster even
if you correct that redundant where functions. here's a one 1d example
for your reference.

x=randomu(systime(1),100)
y=x
t0=systime(1)
for i=0,99 do begin
y[i]=total(1/abs(x[1:99]-x[0]))
x=shift(x,-1)
endfor
print,systime(1)-t0
