How to sub sym to a number in a matrix

Hi all,
I have a code calculate the motion equation of 3DOF robotic arm.
In the code I use symbols such as
q = sym('q', [n 1], 'real');
Eventualy I have a 3x1 vector of the motion using alot of symbols on the way
for example, the output for row 1
val =
qdd2*(Izy2*cos(q1) + Izy3*cos(q1) - Izx2*sin(q1) - Izx3*sin(q1) + m3*(4*cos(q1)*sin(q2) +....
How can I subsitute those symbols, q1,q2,Izy,qdd2 and etc to a number?
I use diff() on the way to do diveration from the symbols (q1,q2,q3).,
so Im looking for a way to put the valuses of the symbols at the end, after calculating the motion equations.
I used sub(), didnt work..
thanks in advance.
