Error when plotting a graph

13 views (last 30 days)
Hello, I am trying to plot the solution to the ordinary second order linear inhomogeneous differential equation:
x''(t)= -x + sin(1.1*t).
I am able to get the solution using the dsolve command, but when I try plotting it using 'plot(x,Solution)', I get an error message saying: 'Warning error updating parametrized function line the following error was reported evaluating the function..' and I can't scroll more to see the full error message.
Any help would be great!

Use fplot if you have R2016a or later, ezplot otherwise.

As always, my pleasure!
You did not call fplot correctly. Compare your call to it, and mine.
Call it as:
fplot(Solution, [0 10])
and it works.
