I'm trying to solve the following differential equation:
y''+y'-6y=20e^t, y(0)=0, y'(0)=1

Then convert the equation of order 2 to a system of equations of order 1 at first. (As Wikipedia or your text book for the simple details on demand.) Then write the function in Matlab and provide it to ode45 (assuming that the equation is not stiff). Try it and then come back to the forum, if you have a specific problem.

Use "dsolve".
