Examples.


The methods are inherited from the GSL. The methods whose names end with j_solver use the jacobian matrix, the rest use approximations for the derivatives.

All methods use an iteration of Newton kind

xn+1=xn
f(xn)
f′(xn)

The four methods hybrid*_solver use also a method of gradient descent when the Newton iteration would make a too large of a step. The length of the step is computed without scaling for hybrid_solver and hybridj_solver or with scaling (computed from f′(xn)) for hybrids_solver and hybridsj_solver.

The rest of this section will cover the various method options.
