Improved Newton method using Bisection method in Python

WebI have tried Fsolve and Scipy optimize lib but no success because no matter which options I used (Fsolve, Scipy Optimize bisection, secant, brentq, ...), they always require different inputs (about which I have no information) Thanks so much in advance. WebJun 12, 2014 · scipy.optimize.fsolve and scipy.optimize.root expect func to return a vector (rather than a scalar), and scipy.optimize.newton only takes scalar arguments. I can redefine func as. def func(x): return [x[0] + 1 + x[1]**2, 0] Then root and fsolve can find a root, but the zeros in the Jacobian means it won't always do a good job.
