Hi,formula)
i am solving a "duffing-like" 2nd order nonlinear diff. equation (in Matlab)
using Dormand-Prince method (based on an explicit Runge-Kutta (4,5)
with variable step. However, how can i be sure that i have chosen a "good
method", i.e. how can i examine the method, i.e. the errors of method used
for solving of my equation?
This is why complete courses are provided
at the graduate level in numerical analysis,
numerical linear algebra, numerical methods
for odes & pdes, etc. Your questions are
studied in depth in those courses.
