rk1_implicit_test

rk1_implicit_test, a C++ code which calls rk1_implicit(), which solves one or more ordinary differential equations (ODE) using the Runge-Kutta order 1 implicit method, using fsolve() to solve the implicit equation, and using a fixed time step. rk1_implicit() is commonly called the backward Euler method.
