I have two arrays, both of which are two-dimensional (for example,

duplicate elements. Any ideas on the best way to do this?

In the past, I've handled this by just dumping the data from the arrays onto
a blank worksheet, sorting the data there, and then doing a search loop that
consolidates the duplicate elements. I'm thinking there might be a way to do
it entirely within arrays, off the worksheet.

I'd do it this way:

go through the smaller array, check for each element if the values
duplicate - if not - redim the bigg array by one, and add the just
processed element.

Does that make sense?
