WebNov 24, 2024 · Zero / root finder using scipy.optimize.fsolve (Python) For functions that have only one tunable variable (other arguments are fixed) It can find any roots from interval (start, stop).; Use relatively small stepsize step to find all the roots. This is used as stepsize for changing the x0 for the fsolve().; Can only search for zeroes in one dimension (other … WebJan 2, 2014 · Try y = z = t = 0 if you don't know anything better. If that doesn't converge, since all the constants in your equations are less than 10, the solution is probably the same order of magnitude. So try something like y = 1, z = 2, t = 3. If it still doesn't converge, try making some or all of the initial values negative.
