WebMay 4, 2024 · Finding intersection of two functions in Python (Scipy, root finding) So I have to write a code to find the intersections between two gaussian functions G1 with the variables (x,0,1) and g2 (x,1,2). I have to find all intersections within x (-5,5) If i take a simpler formula with the code down below it works but like this it gives me errors. 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.
