There is no "first" for a 2D array unless you decide on an order in which to search dimensions.

Easiest would be to reshape the 2D array into a 1D array with a lenght corresponding th the product of the sizes, then use "search 1D array" and calculate the 2D indices from the 1D indices (hint quotient&remainder). 🙂

Here's one of my old examples that you can probably modify for your purpose:

FindFalse2D_Mod.vi  (from this thread.)
