Calculates the fixed point of a univariate function using fixed-point iteration.

Syntax

c = fixed_point_iteration(f,x0)
c = fixed_point_iteration(f,x0,opts)

Description

c = fixed_point_iteration(f,x0) returns the fixed point of a function specified by the function handle f, where x0 is an initial guess of the fixed point. The default tolerance and maximum number of iterations are TOL = 1e-12 and imax = 1e6, respectively.

c = fixed_point_iteration(f,x0,opts) does the same as the syntax above, but allows for the specification of optional solver parameters. opts is a struct that has the following fields:

  • imax → maximum number of iterations
  • return_all → all intermediate fixed point estimates are returned if set to true; otherwise, only the converged fixed point is returned
  • TOL → tolerance
  • warningstrue if any warnings should be displayed, false if not
