How to multiply quaternions with symbols

Hi,

I'm trying to multiply two quaternions with 'quatmultiply'.

But one quaternion contains symbols. So matlab gives an error saying "Error using quatmultiply (line 48) Second input elements are not real."

Below is the code I used,

%%

t2 = sym('t2');

Q12 = quatmultiply([cosd(45) 0 0 sind(45)],[cos(t2/2) sin(t2/2) 0 0])

%%

Is there any other way of computing this?

Thanks

I found the answer. If anyone having the same issue, when specifying the symbol

instead of typing just,

t=sym('t');

Must type

t=sym('t','real');
