dear all,

which is the most efficient way to divide a (long) vector in ranges?


I can't think of nothing better than:

ranges = [  5.5  7.5
	    7.5 10.5
            ...  ...
            50.5  56
             56   64
             64   72 ]

for ii = 1:rows(ranges)
   w = find( v>=ranges(ii,1) & v<ranges(ii,2) );
   ## do something with indices in w
endfor

Any suggestion on how to avoid the for loop?

thanks
Claudio
