As the title says, I need to display the equation of a fitted line (not necessarily on the axes). I have the coefficients of the polynomial thanks to polyfit; is there a sophisticated way to construct an equation from those coefficients? Thanks.

Yes, it would be a symbolic expression. You could disp() it, or pretty() it.
