How do I return the value of a matrix that will be changed by user when use 'openvar' to the variable followed

Here is my piece of code,

clear
clc
display ('Enter your n1');
n1 = input('Enter your n1: ');
display ('Enter your n2');
n2 = input('Enter your n2: ');
A = zeros(n1+n2, n1+n2);
openvar 'A';
x = sum (A,1);
k_out_h = sum (A,2);
k_in_h = x';
k_in_eh = real(k_in_h);
k_in_ch = imag(k_in_h);
k_out_eh = real(k_out_h);
k_out_ch = imag(k_out_h);
a = size(A);
y = a(:,1);
b = [1:y];
c = b';
F = [c, k_in_h, k_in_eh, k_in_ch, k_out_h, k_out_eh, k_out_ch];
disp(F);

I want to calculate the node degree of a adjacency matrix that is specified by user, and display it in workspace.

Now I am aware of the fact that I should wait for a user input (e.g. msgbox or wait for a keypress), or use an = ActiveX-plugin and your own GUI. Does any one have a idea how to implement either of those? Many thanks.
