Nonlinear Root Finding, Equilibrium and Steady-State Analysis of Ordinary Differential Equations R package rootSolve version 1.8.2.4 CRAN Task View: DifferentialEquations (https://CRAN.R-project.org/view=DifferentialEquations) CRAN Task View: NumericalMathematics (https://CRAN.R-project.org/view=NumericalMathematics) 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.
