Polynomial fit with errors (weights) in both axes

Anyone know of code for a polynomial fit with weights in both axes?

Yes, a quick search for total least square at the matlab file exchange gives these (among others):

total least squares method

Regression Utilities

weighted total least squares straight line fit

Look at those, should be what you're looking for.
