The problem I am trying to solve is this:
"Consider the IVP z"+4z'+3z=e^x, z(0)=1 and z'(0)=2. Rewrite it as a system represented by ex3_2ndorder.m. Be sure to put comments after the signature line and wherever else they are needed. Be sure you return a column vector. Use ode45 to solve for z up to x=4."
I am fairly new to MATLAB but the code I wrote is this:
function yprime = ex3_2ndorder(x,y)
%name and date
However, when I try to run it, I get an error message saying "Not enough input arguments. Error in line 4, yprime(1)=y(2);"
Could someone please tell me if my code is correct and why I am receiving this error? Thanks!!
