HI, why is it not work?
xdata=[1];
n=3;
subs(eqn,y,n);
st=solve(eqn,x);
xdata(n)=struct2cell(st);
Error:
Check for missing argument or incorrect argument data type in call to function 'struct2cell'.

if you look at documentation for solve it says the output is a symbolic array.
struct2cell input is struct not symbolic array

solve returns a struct only if you are solving for more than one variable and the number of outputs does not match the number of variables (though 'returnconditions' may affect this)
You are solving for a single variable without returnconditions so you will get a symbolic output not a struct
