Program

clc
clear all
x(1)=randi([6,100]);
x(2)=randi([2,4]);
fun=@(x) x(1)+x(2)+100;
[x, fval]=ga(fun,2)

Output

Optimization terminated: maximum number of generations exceeded.

 x =
  -23.2216  -17.4776
 fval =
   59.3009

here i am getting negative values.. please help how to code this..thank you

Arunachalam - what is the purpose of the code

 x(1)=randi([6,100]);
 x(2)=randi([2,4]);

Do you think that it is necessary for the fitness function that you are trying to minimize, fun? You mention how you are getting negative values for your x. This makes sense since the Genetic Algorithm is minimizing your fitness function. What do you expect to see instead?
