Help required in the code

Hello everyone. I want to change the values of global variable

"global min_realvar ;

global max_realvar" .

For that I want these variables to be assigned as inpput. How I can do this.

Please check the code:

clc

clear all

close all

%initializing global variables used in the model

global nodesize ;

global nreal ;

global nbin ;

global nbits ;

global nobj ;

global ncon ;

global ngen ;
