%description
Routines to find the root of nonlinear functions, and to perform
steady-state and equilibrium analysis of ordinary differential equations
(ODE). Includes routines 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 dynamically running, (4) solve the
steady-state conditions for uni-and multicomponent 1-D, 2-D, and 3-D
partial differential equations, that have been converted to ordinary
differential equations by numerical differencing (using the
method-of-lines approach). Includes fortran code.
