Weighted linear regression

[ptengineer]

I need a weighted linear regression performed on some data and polyfit doesn't provide weighted linear regression functionality. Does anyone know how to code this in matlab and if so provide the code or some hints as to how?

If you want some help you'd best do some of the legwork by defining WLR properly
