• Class Summary
Class Description
ODE
An ordinary differential equation (ODE) is an equation in which there is only one independent variable and one or more derivatives of a dependent variable with respect to the independent variable, so that all the derivatives occurring in the equation are ordinary derivatives.
ODE1stOrder
A first order ordinary differential equation (ODE) initial value problem (IVP) takes the following form.
ODE1stOrderWith2ndDerivative
Some ODE solvers require the second derivative for more accurate Taylor series approximation.
