Chapter 2 Errors in Numerical Methods
www.engr.mun.caAnalytical solution: an exact answer in the form of a mathematical expression in terms of the variables associated with the problem. 2) Numerical solution: an approximate numerical value (a number) for the solution. For a problem to be solved numerically, you may choose several numerical methods which differ in accuracy, time of calculation.
Solving Differential Equations in R - The R Journal
journal.r-project.orgNumerical accuracy Numerical solution of a system of differential equa-tions is an approximation and therefore prone to nu-merical errors, originating from several sources: 1.time step and accuracy order of the solver, 2.floating point arithmetics, 3.properties of the differential system and stabil-ity of the solution algorithm.
