But I want to create a symbolic matrix that is symmetric.
I learned how to make a non-symmetric symbolic matrix thus:
>> n=3;
>> Q = sym('q', [n n])
Q =
[ q1_1, q1_2, q1_3]
[ q2_1, q2_2, q2_3]
[ q3_1, q3_2, q3_3]
Now I want to know if there is an easy way to make this:
Q =
[ q1_1, q1_2, q1_3]
[ q1_2, q2_2, q2_3]
[ q1_3, q2_3, q3_3]
