Hi,
I want to write the first and second derivative with the legend command like this y' y''
This is what I tried:
legend ('y'(0)', 'y''(0)')
but the ' and '' after y interferes with the command.
I tried to search around for answers but found nothing I understood so this is my last resort!
And thanks in advance for the help.

legend({'$\dot{y}(0)$', '$\ddot{y}(0)$'}, 'Interpreter', 'latex')
