Trying to code two angular acceleration equations and angles

I wrote
%initial condition of theta angle (precession angle) tt (1) = 0.5;
ttd (1) = 0; ttdd (1) = 0;
el (1) = 0;
eld (1) = (m*g*sin(tt(1)))/(C*omega_s); eldd (1) = 0;
for
ttdd(i+1) =(M_y-((C*omega_s*sin(tt(i)))*((M_x-(C*ttd(i)*omega_s)+(A*eldd(i)*sin(tt(i))))/(((-2)*A*ttd(i)*cos(tt(i)))+(C*ttd(i)*cos(tt(i)))))));
eldd (i+1) = (M_x+ ((2*A*ttd(i)*cos(tt(i)))*((M_y-(A*ttdd(i)))/(C*omega_s*sin(tt(i)))))-(C*ttd(i)*omega_s)-(C*ttd(i)*((M_y-(A*ttdd(i)))/(C*omega_s*sin(tt(i))))*cos(tt(i))));
ttd(i+1) = (ttdd(i+1)*delta_t)+ttd(i);
tt (i+1) = ((ttd(i+1)*delta_t))+tt(i);
eld(i+1) = (eldd(i+1)*delta_t)+eld(i);
el (i+1) = ((eld(i+1)*delta_t))+el(i);
in the Matlab.
end
My inputs are M_x and M_y and trying to get the angles as outputs. All my answers are NAN... Please point out where I got wrong. Thanks

complete your for loop. what is
for
in your program? also, give all data to allow testing your code

To give you a hint, 1/0 = Inf, 0/0 = NaN. So you need to avoid doing these things in your code.
Special case the situations when you have a potential 0/0 should solve your problem.
