Tabu search in matlab?

I want to ask you about the tabu search code,
I can use the simulated annealing to find the minimum value of the function f (a,b)

f(a,b) =2*(a^2+b^2)+(a*b)-5*(a+b)

The answer = -5 , a =1 , b =1

But I found difficulty to writ the m. file of tabu search in matlab code to find the answer for the same function.

Regards
