What is ode45 in MATLAB?

brief introduction to using ode45 in MATLAB brief introduction to usingode45inMATLAB MATLAB's standard solver for ordinary dierential equations (ODEs) is the functionode45. This function implements a Runge-Kutta method with a variable time step forecient computation. ode45is designed to handle the following general problem:

What is ode45 used for?

Now ode45 is used to perform simulation by showing the solution as it changes intime. Given a single degree of freedom system. This represents any engineering system whose responsecan move in only one direction. A typical SDOF (single degree of freedom) is the followingmass/spring/damper system.

Can ode45 solve a higher order ODE?

The matlab function ode45will be used. The important thing to remember is that ode45 can only solve a ?rst order ODE. Therefore to solve a higher order ODE, the ODE has to be ?rst converted to a set of ?rst orderODE’s. This is possible since an (n) order ODE can be converted to a set of (n) ?rst orderODE’s.

What is ode45 tspan TF?

[t,y] = ode45 (odefun,tspan,y0) , where tspan = [tt0 tf], integrates the system of differential equations y = f ( t, y) from t0 to tf with initial conditions y0. Each row in the solution array y corresponds to a value returned in column vector t.
