Solving the above system is only possible in the form
M = [1 0 0 0 0; ...
0 m1 0 0 0; ...
0 0 1 0 0; ...
0 0 0 m2 0; ...
0 m2*tan(theta) 0 -m2*tan(theta) 0];
f = [y2 ; -sin(theta)*N ; y4 ; sin(theta)*N ; -m2*g+cos(theta)*N];
M*[y1dot ; y2dot ; y3dot ; y4dot ; Ndot] = f(y1,y2,y3,y4,N)
But you might get the message from the integrator that the index of the system is >1.
Test it.
