James Bence commented on MATH-552: ---------------------------------- To resolve this, replace lines 198 through 204: int idx = 1; while (count < index) { count += idx; idx += 1; } --idx; indices[last] = idx; with the following: indices[last] = index - count; > MultidimensionalCounter.getCounts(int) returns wrong array of indices > --------------------------------------------------------------------- > > Key: MATH-552 > URL: https://issues.apache.org/jira/browse/MATH-552 > Project: Commons Math > Issue Type: Bug > Affects Versions: 2.2 > Environment: Java 1.6 > Reporter: James Bence > Priority: Minor > > MultidimensionalCounter counter = new MultidimensionalCounter(2, 4); > for (Integer i : counter) { > int[] x = counter.getCounts(i); > System.out.println(i + " " + Arrays.toString(x)); > } > Output is: > 0 [0, 0] > 1 [0, 1] > 2 [0, 2] > 3 [0, 2] <=== should be [0, 3] > 4 [1, 0] > 5 [1, 1] > 6 [1, 2] > 7 [1, 2] <=== should be [1, 3] -- This message is automatically generated by JIRA.
