Solve systems of eqns

Hi, I tried solving a system for:
if true
% code
end
eqns = h^2*[diff(y,t)+2*i*g*y+g^2==0, diff(z,t)==y];
sol = dsolve(eqns)
and get:
>> Solve_Systems_of_ODE
h = 2 g =
5
sol =
struct with fields:
z: [1×1 sym]
y: [1×1 sym]
what does this result mean really?
Thanks

Hi Sergio,
syms y(t) z(t)
h=4.5;
g=4/pi;
eqns=h^2*[diff(y,t)+2*i*g*y+g^2==0,diff(z,t)==y];
sol=dsolve(eqns);
y=vpa(sol.y,4)
z=vpa(sol.z,4)
I assume that the numeric constants are the same with previous question, the struct sol actually holds the solution of these diff equation set wrt y and z respectively. Actually it has solution. Why don't you check it once more?
