The Euler Method. Let d S ( t) d t = F ( t, S ( t)) be an explicitly defined first order ODE. That is, F is a function that returns the derivative, or change, of a state given a time and state value. Also, let t be a numerical grid of the interval [ t 0, t f] with spacing h. Without loss of generality, we assume that t 0 = 0, and that t f = N h ...
Implicit Methods for Linear and Nonlinear Systems of ODEs
web.mit.edu/16.90/BackUp/www/pdfs/Chapter9.pdf
Implicit Methods for Linear and Nonlinear Systems of ODEs In the previous chapter, we investigated stiffness in ODEs. Recall that an ODE is stiff if it exhibits behavior on widely-varying timescales. Our primary concern with these types of problems is the eigenvalue stability of the resulting numerical integration method.
