%
%  x=fsolve('f',x0,options,'g') finds the value of x for which f(x) is zero.
%  options is optional, giving the optimization arguments. If options
%  is the empty matrix, default options are used.
%  g(x) provides the optional gradient of the function f(x). Optional 
%  arguments may be provided to f by passing them to fsolve after 'g'.
