I used the follwing code to solve a equation but the data is in a symbolic matrix format.

syms a

f=solve((c3(i)*a^3)+(c2(i)*a^2)-c1(i))

The output is in a symbolic matrix format.

How to read the data from symbolic matrix? I want to load the data to variables a,b and c.

Thanks

What about

a = double(f(1));
b = double(f(2));
c = double(f(3));

? This will substitute in values for a b and c. Then you could use double() or vpa() to convert to numeric form.
