Homework Statement
Consider the following second order ODE
$$ y'' + 2y'  y = e^{x}, \quad y(0) = y'(0) = 1. $$ Convert this to a system of first order equations and use the pc33assisys MATLAB file to compute the solution for y(2).
Homework Equations
The Attempt at a Solution
The system of first order equations is
$$ u_1' = u_2 \\ u_2' = e^{x}2u_2+u_1 $$ with $$ u_1(0) = u_2(0) = 1. $$
The solution for y(2) is y(2) = 3.27 to 2 d.p. But my pc33assisys file doesn't give me this. All the relevant files are attached to run the program. Can someone help figure out what is wrong with my code.
Thanks.
