I know that there are some Technic for finding curve fitting like polyfit() or pinv(). so we can get a some polynomial equation. it's OK good.
I can get successively a polynomial equation for each curve by using polyfit() or pinv()..it easy. no problem.
But my problems is here.
Actually I want to know a concept to make one equation which from all polynomial equations.
for example, if I get 3 equations(curve #1's equation ,curve #2's equation ,curve #3's equation) then I want to make all in one equation.\
Is this possible? what kinds of Technic is exist?
I've got 4 polynomials
But I'm not sure how to apply your way about extracting the corresponding parameters. Would you please help me a small bit more ?
