Summary

Find a root of a function, using a tuned diagonal Jacobian approximation.

Extended Summary

The Jacobian matrix is diagonal and is tuned on each iteration.

Parameters

%(params_basic)s
alpha : float, optional: Initial Jacobian approximation is (-1/alpha).
alphamax : float, optional: The entries of the diagonal Jacobian are kept in the range [alpha, alphamax].
