Hello,
I would like to be able to modify an array in modifying a subarray. For example, I have these 3 arrays :
a = [1; 2];
b = [3 5; 4 6];
c = [a b];
When I modify a column of b,
b(:,1) = [6 8];
I would like that c changes too and becomes : [1 6 5; 2 8 6]. Whereas currently c remains [1 3 5; 2 4 6]...
How can I do that ?

There is no easy way to do such a thing in MATLAB. The closest you can get is to define your own class and add event listeners to react whenever there is a change in the value of b. That will require a fair share of understanding of MATLAB OOP.

Hi....
I am not sure I understood your question properly but I wrote something as per my initial understanding to get your results.
a = [1; 2];
b = [3 5; 4 6];
b(:,1) = [6 8];
c = [a b];
disp(c);
