I have a long code which has syms like q1(t) q2(t) ...
I have a 3x1 matrix which is in format like: n1=a1*q3(t)
a2*sin(q2(t)
0
How can i call the second row? Because when i try to call it like n1(2,1), algorithm perceive it as i attend a value to t.

Ran in:
syms t q2(t) q3(t) a1 a2
n1 = [a1*q3(t);a2*sin(q2(t));0];
n1(2,1) % extract element (2,1)
ans = 
n1(2,:) % extract complete 2nd row
ans =
