Is there a quick way to sort a single dimensional array? Multi-dimensional
array?
Thanks.

Bernie

Bernie,

Stephen Bullen has a good collection of QuickSort routines:

HOWTO: Sort Algorithms for Numeric Arrays

Here is some code I have modified to do it.

The second procedure shows how to call the quicksort.

Sub QuickSort(SortArray, col, L, R, bAscending)

'Modified to sort on first column of a two dimensional array

'Modified to do Ascending or Descending
Dim i, j, X, Y, mm

i = L
j = R
X = SortArray((L + R) / 2, col)
If bAscending Then
While (i <= j)
While (SortArray(i, col) < X And i < R)
i = i + 1
Wend
While (X < SortArray(j, col) And j L)
j = j - 1
Wend
If (i <= j) Then
For mm = LBound(SortArray, 2) To UBound(SortArray, 2)
Y = SortArray(i, mm)
SortArray(i, mm) = SortArray(j, mm)
SortArray(j, mm) = Y
Next mm
i = i + 1
j = j - 1
End If
Wend
Else
While (i <= j)
While (SortArray(i, col) X And i < R)
i = i + 1
Wend
While (X SortArray(j, col) And j L)
j = j - 1
Wend
If (i <= j) Then
For mm = LBound(SortArray, 2) To UBound(SortArray, 2)
Y = SortArray(i, mm)
SortArray(i, mm) = SortArray(j, mm)
SortArray(j, mm) = Y
Next mm
i = i + 1
j = j - 1
End If
Wend
End If
If (L < j) Then Call QuickSort(SortArray, col, L, j, bAscending)
If (i < R) Then Call QuickSort(SortArray, col, i, R, bAscending)
End Sub




Sub aaTesterSort()
Dim bAscending As Boolean
Set rng = Range("I7").CurrentRegion
vArr = rng.Value
bAscending = False
QuickSort vArr, 5, LBound(vArr, 1), UBound(vArr, 1), bAscending
Range("I26").Resize(UBound(vArr, 1), UBound(vArr, 2)).Value = vArr
End Sub

Hi Bernie,

I found this thread before..there are many ways of sorting arrays.
(As far as I saw, 1-D array only)
