Using Symbolic math toolbox online?

I have bought Matlab and use it online. Now bought the symbolic math toolbox but can't find it working online. Can it be done and if so what do I need to do?

Do you mean MATLAB Online? It doesn't require you to download any toolboxes separately. What error message do you get when you do

syms SYMBolic woRks
SYMBolic == woRks % ?

syms(r1,r2,r3,u1,u2,b1,b2,a1,a2,y)

J = [r1-y, u1, -a1; u2, r2-y, -a2; b1, b2, r3-y]

det_J = det(J);
y_values = solve(det_J == 0, y);
y_values

It seems unlikely that would work. That syms() call requires that all of the named variables already be defined. It is more likely that you would want

syms r1 r2 r3 u1 u2 b1 b2 a1 a2 y
