WebApr 10, 2024 · After a painful googling, I got a suggestion to use scipy.optimize. However, if I use method 'secant', it's not compatible with the original function in Matlab because the algorithm is 'bisection, interpolation'. If I use method = 'bisect', a bracket is required, which I don't know because I cannot see any bracket in the original program in Matlab.
