How can I find the intersection points between the solution of a 3rd order ODE and a line y=x?
My ODE's code is
sol=dsolve('D3y-4*D2y+Dy+2*y=0,y(0)=-4,Dy(0)=-6,D2y(0)=-4')x=0:2y=subs(sol,'t',x)plot(x,y)
interserction pointsodethird order
sol=dsolve('D3y-4*D2y+Dy+2*y=0,y(0)=-4,Dy(0)=-6,D2y(0)=-4')x=0:2y=subs(sol,'t',x)plot(x,y)
