Octave is case sensitive and you have a small x above this line and a large X below this line!!!
Change to large X every where!
y = zeros (12, 1);
y(1) = Y_e*X(1)*sin(X(2)) +dStat*X(5)/2 + O;
y(2) = X(4) -X(3) + Og_o;
y(3) = X(7);
y(4) = X(1)*Tau^2*(Og_o + X(3))*X(4) +Cf*X(8);
y(5) = X(9) -X(3)*Tau*Y_e*X(1);
y(6) = X(10) -abs(X(3)*Tau*Y_e*X(1))*L_cm/Tau;
y(7) = X(11) -W_cm/X(10);
y(8) = X(12) -Thic_cm/X(10);
y(9) = X(6) -Ogto*X(3)*X(11);
y(10) = X(13) -Mpi*(-D1)*((X(3)*tau*Y_e*X(1)))*(1 - sin(X(2)));
...
...
y(51) = X(8) -X(39) -X(40) -X(41) -X(42) -X(43) -X(44) -X(45) -X(46) -X(47)
-X(48) -X(49) -X(50)
