I tried to do it this way, but it does not work. How can I fix it?

Hi Gaetano,
What doesn't work?
As far as I can tell, that code takes in the state variables and outputs their derivatives, which are presumably integrated outside the function.
Also, there is no need to compute Minv explicitly. Instead, that last line could be
[xdot_3,xdot_4] = M_theta \ [same stuff here];

Hi Paul,
Thank you for your reply.
It gives me this error, I cannot understand why.

One problem that I should have seen before is that this line
[xdot_3,xdot_4] = Minv * [same stuff here];
should be
temp = M_theta \ [same stuff here];
xdot_3 = temp(1);
xdot_4 = temp(2);
Does that solve all of the problems?
