The following is a Transpose function; you can judge its robustness for
yourself:

Function ArrayTranspose(InputArray)
'This function returns the transpose of
'the input array or range; it is designed
'to avoid the limitation on the number of
'array elements and type of array that the
'worksheet TRANSPOSE Function has.

'Declare the variables
Dim outputArrayTranspose As Variant, arr As Variant, p As Integer
Dim i As Long, j As Long

'Check to confirm that the input array
'is an array or multicell range
If IsArray(InputArray) Then

'If so, convert an input range to a
'true array
arr = InputArray

'Load the number of dimensions of
'the input array to a variable
On Error Resume Next

'Loop until an error occurs
i = 1
Do
z = UBound(arr, i)
i = i + 1
Loop While Err = 0

'Reset the error value for use with other procedures
Err = 0

'Return the number of dimensions
p = i - 2
End If

If Not IsArray(InputArray) Or p 2 Then
Msg = "#ERROR! The function accepts only multi-cell ranges and
1D or 2D arrays."
