Find a root of a function, using Broyden's first Jacobian approximation.

This method is also known as \'Broyden's good method\'.

Parameters ---------- %(params_basic)s %(broyden_params)s %(params_extra)s

See Also -------- root : Interface to root finding algorithms for multivariate functions. See ``method=='broyden1'`` in particular.

Notes ----- This algorithm implements the inverse Jacobian Quasi-Newton update

.. math:: H_+ = H + (dx - H df) dx^\dagger H / ( dx^\dagger H df)

which corresponds to Broyden's first Jacobian update

.. math:: J_+ = J + (df - J dx) dx^\dagger / dx^\dagger dx
