Matlab’s Function ode45. Matlab has several built-in ODE solvers. One particular solver, called ode45, which is based on fourth- and fifth-order Runge-Kutta methods. The function can solve a single first-order ODE or a system of ODEs. The basic call has the syntax: [t,y]=ode45(fun, tspan, y0), where y is the numerical solution array where each

Bucknell University Using ODE45 5 you see that t (the independent variable) is the first input, as required by ode45 and other solvers.If you do not specify the order, inline will rely on a default method of setting the order that may not be what you want. As long as € f(t,y) is simple (e.g., it does not require extra parameters or too many steps to evaluate), it’s

[t,y,te,ye,ie] = ode45(odefun,tspan,y0,options) additionally finds where functions of (t,y), called event functions, are zero. In the output, te is the time of the event, ye is the solution at the time of the event, and ie is the index of the triggered event. For each event function, specify whether the integration is to terminate at a zero and whether the direction of the zero crossing matters.

First create a MatLab function and name it fun1.m . function f=fun1(t,y) f=-t*y/sqrt(2-y^2); Now use MatLab functions ode23 and ode45 to solve the initial value problem numerically and then plot the numerical solutions y, respectively.
