excel - VBA using ubound on a multidimensional array

Question

Ubound can return the max index value of an array, but in a multidimensional array, how would I specify WHICH dimension I want the max index of?

For example

Dim arr(1 to 4, 1 to 3) As Variant

In this 4x3 array, how would I have Ubound return 4, and how would I have Ubound return 3?

Answer 1

ubound(arr, 1) 

and

ubound(arr, 2)
