RE: Using fsolve() to solve non-linear system equation
(06-24-2019 05:53 PM)parisse Wrote: For univariate equations, a sign change on an interval warrants a root for a continuous fonction, it's not hard to implement a numeric solver on an interval. There is unfortunately no easy generalization for multivariate fonctions. That's why there is only an iterative implementation for generic systems, requiring a initial guess. However, polynomial systems like your system can be solved without initial guess with solve or fsolve (with [x,y] as 2nd argument). Can a wrong initial guess eliminate the possibility of a solution? If not then why not let the machine make the guess internally? Tom L Cui bono? |
