The MATLAB ODE solvers are designed to handle ordinary differential equations. These are differential equations containing one or more derivatives of a dependent variable ywith respect to a single independent variable t, usually referred to astime. The derivative of ywith respect to tis denoted as, the second derivative as, and so on. Ordinary Differential Equations .

(ODE = ordinary differential equation) I am afraid Description. ode solves explicit Ordinary Different Equations defined by:. It is an interface to various solvers, in particular to ODEPACK. In this help, we only describe the use of ode for standard explicit ODE systems.. The simplest call of ode is: y = ode(y0,t0,t,f) where y0 is the vector of initial conditions, t0 is the initial time, t is the vector of times at which the solution y is An ordinary differential equation (ODE) is an equation involving some ordinary derivatives of a function (as opposed to partial derivatives). In comparison to the term partial differential equation that might be in relation to more than one independent variable, the term ordinary is used.
