3540 | Robustess: quadratic convergence |

3544 | |
---|
3545 | Method: |
---|
3546 | look for closed orbit solution of f(x) = x |
---|
3547 | This problems is equivalent to finding the zero of g(x)= f(x) - x |
---|
3548 | g(x+h) ~= f(x) - x + (Jacobian(f) -Id) h + O(h*h) |
---|
3549 | Then at first order we solve h: |
---|
3550 | h = - inverse(Jacobian(f) -Id) * (f(x)-x) |
---|
3551 | the new guess is then xnew = x + h |
---|
3552 | By iteration, this converges quadratically. |

3554 | The algo is stopped whenever |x -xnew| < tolx |

3635 | /* int Newton_Raphson(int n, double x[], int ntrial, double tolx) |
---|
3636 | |
---|
3637 | Purpose: |
---|
3638 | Newton_Rapson algorithm from Numerical Recipes |
---|
3639 | double precision algorithm |
---|
3640 | Robustess: quadratic convergence |
---|
3641 | Hint: for n-dimensional problem, the algo can be stuck on local minimum |
---|
3642 | In this case, it should be enough to provide a resonable starting |
---|
3643 | point. |
---|
3644 | |
---|
3645 | Method: |
---|
3646 | look for closed orbit solution of f(x) = x |
---|
3647 | This problems is equivalent to finding the zero of g(x)= f(x) - x |
---|
3648 | g(x+h) ~= f(x) - x + (Jacobian(f) -Id) h + O(h*h) |
---|
3649 | Then at first order we solve h: |
---|
3650 | h = - inverse(Jacobian(f) -Id) * (f(x)-x) |
---|
3651 | the new guess is then xnew = x + h |
---|
3652 | By iteration, this converges quadratically. |
---|
3653 | |
---|
3654 | The algo is stopped whenever |x -xnew| < tolx |
---|
3655 | |
---|
3656 | f(x) is computes by tracking over one turn |
---|
3657 | Jacobian(f) is computed numerically by numerical differentiation |
---|
3658 | These two operations are provided by the function computeFandJ |
---|
3659 | |
---|
3660 | Input: |
---|
3661 | ntrial number of iterations for closed zero search |
---|
3662 | x intial guess for the closed orbit |
---|
3663 | tolx tolerance over the solution x |
---|
3664 | tolf tolerance over the evalution f(x) |
---|
3665 | |
---|
3666 | Output: |
---|
3667 | x closed orbit |
---|
3668 | |
---|
3669 | Return: |

3670 | none |
