Is there a reliable package for solving simple equation system?

  1. Please read: make it easier to help you. It will help you get answers in this forum if you read this and follow its recommendations. For example, post code for a minimum working example rather than just describing your problem.
  2. It’s too much to expect a nonlinear solver to find all solutions. There is no upper bound on the number, location, narrowness, degree, etc of the roots of arbitrary nonlinear functions. Instead solvers typically find a single solution near a given initial guess. Try running NLSolver with an initial guess near the other solution.
  3. Julia is sensitive to whitespace in a number of ways. You’ll need to provide more details (e.g. the code and where you changed whitespace) to get help on that.
