# `fixed_point_iteration`

Fixed-point iteration for finding the fixed point of a univariate, scalar-valued function.

## Syntax

`c = fixed_point_iteration(f,x0)`
`c = fixed_point_iteration(f,x0,opts)`
`[c,k] = fixed_point_iteration(__)`
`[c,k,c_all] = fixed_point_iteration(__)`

## 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.

`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 structure with the following fields:

• `k_max` → maximum number of iterations (defaults to 200)
• `return_all` → returns estimates at all iteration if set to `true` (defaults to `false`)
• `TOL` → tolerance (defaults to )

`[c,k] = fixed_point_iteration(__)` also returns the number of iterations (`k`) performed of fixed-point iteration.

`[c,k,c_all] = fixed_point_iteration(__)` does the same as the previous syntaxes, but also returns an array (`c_all`) storing the fixed point estimates at each iteration. This syntax requires that `opts.return_all` be set to true.
