Algorithm behind regionprops for fitting ellipse?

I've just fit an ellipse to an arbitrary shape in an image by using the properties resulting from regionprops.
However I'm unsure of the algorithm behind how it finds these properties, as I need to justify the fit. Any ideas??

Perhaps it's similar to what's in the FAQ. Another way to justify it is to run through a bunch of shapes and see if you agree with the ellipses it provides. If you agree, then you've validated it, at least as far as necessary for your purposes.

edit regionprops
And search for where it computes the ellipses. In R2012b, line 626:706.
