Routines to find the root of nonlinear functions, and to perform steadystate and equilibrium analysis of ordinary differential equations (ODE). Includes routines that: (1) generate gradient and jacobian matrices (full and banded), (2) find roots of nonlinear equations by the 'NewtonRaphson' method, (3) estimate steadystate conditions of a system of (differential) equations in full, banded or sparse form, using the 'NewtonRaphson' method, or by dynamically running, (4) solve the steadystate conditions for uniand multicomponent 1D, 2D, and 3D partial differential equations, that have been converted to ordinary differential equations by numerical differencing (using the methodoflines approach). Includes fortran code.
