Functions that:
(1) generate gradient and Jacobian matrices (full and banded),
(2) find roots of non-linear equations by the Newton-Raphson method,
(3) estimate steady-state conditions of a system of (differential) equations in full, banded or sparse form, using the Newton-Raphson method or by a dynamic run,
(4) solve the steady-state conditions for uni-and multicomponent 1-D and 2-D reactive transport models (boundary value problems of ODE) using the method-of-lines approach.
