Second order differential equation

Hi I want to solve a differential equation in matlab and plot the solution

y”-Ay+B=0 initial condition y(1)=35.5 and A and B are known contant values.

Have you looked at the examples in the ode45 doc? What is the y' initial condition?

If you need help, see the documentation for the ode45 function to understand how to convert it to a system of two first-order differential equations.

The Symbolic Math Toolbox can also help. First, write it as a symbolic second-order differential equation. Then use the odeToVectorField and matlabFunction functions to create it as a system of two first-order differential equations that you can solve with ode45.
