Subject [jira] Created: (MATH-379) Multidimensional counter
Date Thu, 24 Jun 2010 11:19:50 GMT
Multidimensional counter
------------------------

                 Key: MATH-379
                 URL: https://issues.apache.org/jira/browse/MATH-379
             Project: Commons Math
          Issue Type: New Feature
            Reporter: Gilles
            Assignee: Gilles
            Priority: Minor


Utility that converts from indices in a multidimensional structure to the corresponding index
in a one-dimensional array.

E.g. assuming that the ranges (in 3D) of indices are {2, 4, 3}, we'll have that
  (0, 0, 0) corresponds to 0
  (0, 0, 1) corresponds to 1
    ...
  (1, 0, 0) corresponds to 12
    ...
  (1, 3, 2) corresponds to 23

I propose to add this class in the "util" package.
