Curve Fitting

FITTING

def quadratic(x,A,B,C)
    return A*x**2 + B*x + C

A,B,C = optimize.curve_fit(quadratic, x, y)[0]
y_ = A*x**2 + B*x + C

THE OBJECT FUNCTION SHOULD BE DEFINE FIRST THE SUITABEL WILL AFFECT THE FINAL RESULT DIRECTLY

HERE, IN QUANTUM PHYSICS, CHEMICAL, IT IS NOT RECOMMENDED

THE RECOMMENDED WAY IS lmfit

请采用Origin，别想某胡博后，哈哈哈哈

THE EQUATION SHOULD BE COMPLEX IF YOU NEED TO KNOW HOW TO COMPUTE AND THE DISADVANTAGE OF origin IS YOU WOULD NOT KNOW HOW YOU GET IT

\[span = A2 - A1\] \[y1 = span * \frac{p}{1 + 10^{(l_1 * h_1)}}\] \[y2 = span * \frac{1-p}{1 + 10^{(l_2 * h_2)}}\] \[y = A1 + y1 + y2\]
