Root of nonlinear function

The `fzero`

command
is a function file. The algorithm, created by T. Dekker,
uses a combination of bisection, secant, and inverse quadratic interpolation
methods. An Algol 60 version, with some improvements, is given in [1]. A Fortran version, upon which `fzero`

is
based, is in [2].

The **Optimize** Live Editor task provides a visual interface for
`fzero`

.
