when I run this bellow code, it shows this error,
syms x a=solve(x^2+4*x+4); b=a(1) if b>2 s=2 else s=3 end
Undefined function or method 'gt' for input arguments of type 'sym'.
Error in ==> solution at 4 if b>2
my target is, I have to compare the value of 'x' in the equation with constant. but I got this error.
please help me the solution for my problem..

If you want numeric answers, work numerically:
a = roots([1, 4, 4]);
solve() does not return numbers: it returns formula, some of which happen to print out like numbers. If you happen to get a solve() result that involves only known functions of constants, then you can use double() on the result to calculate the double-precision approximation of the result.
By the way, you should not assume that the results of solve() are returned in any particular order.
