Hi, look up "BinLists" and "BinCounts" in the manual. Mathematica Version 6 has more comfortable versions of these routines. hope this helps, Daniel R.G wrote: > Hi Mathgroup members, > > Say, I have a list with the following elements: > > A={6.32553, 7.09956, 8.56784, 16.1871, 15.3989, 17.2285, 7.40711, \ > 14.8876, 19.9068, 10.0834} > > and I have the following list with each {xvalue, yvalue}={lower bound, > upper bound}: > B={{0, 7}, {8, 10}, {11, 12}, {13, 15}, {16, 18}} > > How can I segregate values in A according to lower bound and upper > bound from B and find the number number of occurrence ?For example: > {0,7}={6.32553}, thus the number of occurrence is 1. > {8, 10}={7.09956,7.40711,8.56784}, the number of occurrence is 3. > {11,12}=None, the number of occurrence is 0. > > The code should be able work for any number Length[A] and Length[B]. > Any suggestion please? > Thank you, > R.G > >
