All MATLAB ® ODE solvers can solve systems of equations of the form y ' = f (t, y), or problems that involve a mass matrix, M (t, y) y ' = f (t, y). The solvers all use similar syntaxes. The ode23s solver only can solve problems with a mass matrix if the mass matrix is constant.

• An ODE is an equation that contains one independent variable (e.g. time) and one or more derivatives with respect to that independent variable. • In the time domain, ODEs are initial-value problems, so all the conditions are specified at the initial time t = 0. • Matlab has several different functions (built-ins) for the numerical

The basic usage for MATLAB’s solver ode45 is ode45(function,domain,initial condition). That is, we use >>[x,y]=ode45(f,[0 .5],1) and MATLAB returns two column vectors, the first with values of x and the second with values of y. (The MATLAB output is fairly long, so I’ve omitted it here.) Since x and y are

Choose an ODE Solver Ordinary Differential Equations. An ordinary differential equation (ODE) contains one or more derivatives of a dependent variable, y, with respect to a single independent variable, t, usually referred to as time.The notation used here for representing derivatives of y with respect to t is y ' for a first derivative, y ' ' for a second derivative, and so on.

Solve Differential Equation with Condition. In the previous solution, the constant C1 appears because no condition was specified. Solve the equation with the initial condition y(0) == 2.The dsolve function finds a value of C1 that satisfies the condition.
