Is there some way within IDL to do the following while avoiding the
inefficiency of using IDL loops?

rows = 135
cols = 203
ratio = 10
values = 8

summary = DBLARR(values, cols, rows)
data = DBLARR(cols*ratio, rows*ratio)

FOR row=0,rows-1 DO BEGIN
FOR col=0, cols-1 DO BEGIN
summary[col,row,*] = HISTOGRAM(data[ratio*col:(ratio*col+1), $
ratio*row:(ratio*row+10), MIN=1, MAX=VALUES)
ENDFOR
ENDFOR
