30 Given @var{fcn}, the name of a function of the form @code{f (@var{x})}
31 and an initial starting point @var{x0}, @code{fsolve} solves the set of
32 equations such that @code{f(@var{x}) == 0}.

36 When called with two arguments, this function allows you set options
37 parameters for the function @code{fsolve}. Given one argument,
38 @code{fsolve_options} returns the value of the corresponding option. If
39 no arguments are supplied, the names of all the available options and
40 their current values are displayed.
