Polynomial roots

[Inderpreet Arora]

Hello,
I want to compare roots of a polynomial with a number. But it gives error. Consider a simple e.g.,

a = [2 3];
s = %s;
x = s^2 - 5*s + 6;
r = roots(x); r1 = [roots(x)]';
t1 = type(a);
t2 = type(r);
a > 2
r > 2

It does the comparison for a (done for verification) but gives the following error for r and r1, though their types are same,

Undefined operation for the given operands
check or define function %s_2_s for overloading

I tried in versions 4.1 and 4.1.2. Please guide. Thanks.

Sincerely,
Inderpreet
