%LEASTSQ Non-linear least squares
%
%  x=leastsq('f',x0,options,'g') finds the value of x which minimizes 
%  the sum of squares of f(x) value. 
%  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 leastsq after 'g'.
