Can someone help with a hint of this question using MATLAB?

I suppose you want to limit your case to bi-dimensional arrays.
You can create a function which works for every matrix
function A = createCopyWithNullLastColumn(A)
% Change values of last column :
A(:,end) = 0;
end
Or go with the script:
% Create random matrix <A>:
A = rand(randi([1,10]), randi([1,10]));
% Create a copy <B> of <A>:
B = A;
% Set last column of <B> equal to <0>:
B(:,end) = 0;

Please don't do obvious homework assignments for students. This never helps the student, who learns nothing more than they can find someone willing to do their work for them, if they only plead sadly enough.
It does not help the site, since it convinces that student to continue to post their homework assignments, with no effort made.
Worse, it actively hurts the site, because then it convinces other students they have the right to post their homework assignments too. You then help to turn answers into a site where nothing is seen except for students angrily demanding that we do their homework for them, and do it quickly.
If you feel compelled to help, then offer some guidance. Push them in the right directino. Here, you might have suggested they create a smaller random matrix, and then append zeros, or something like that, but NOT write the code for them.
