Find a root of a function, using diagonal Broyden Jacobian approximation.
The Jacobian approximation is derived from previous iterations, by retaining only the diagonal of Broyden matrices.
Warning
This algorithm may be useful for specific problems, but whether it will work may depend strongly on the problem.
