how can you perform curve fitting to a 2d array and find the maximum?

Altenbach,

In message #9 of this discussion you mention "If your model is more complex, (e.g. a 2D gaussian over a 2D polynomial background), You can use Levenberg Marquardt. I made a simple demo for NI week".  Can you please post this vi because it sounds like it's exactly what I'm looking for.  Thank you very much!

I thought I posted it before, but I don't remember where. Here's an old version (I just changed some cosmetics and downconverted to LabVIEW 8.2 again)
