Now that we’ve solved the ode, suppose we want to plot the solution to get a rough idea of its behavior. For applied problems, numerical methods for ordinary differential. Ode boundary value problem statement¶.

Time) And One Or More Derivatives With Respect To That Independent Variable.

The solvers evaluate the derivatives in the ode function many times. For a stiff problem, solutions can change on a time scale that is very short compared to the interval of integration, but the solution of interest changes on a much longer time scale. Stiff ode problemsthis section presents a stiff problem.
