In the code below, when a, a variable in matrix w, is updated the matrix does not automatically update. Is there a way to update it as a changes automatically?
a = 5;
w = [a 5 6]
a = 6
w

Ran in:
You can do it with some object-oriented programming trickery, but in the long run, I don't think it's going to be what you want.
a=handleMatrix([15,1]) %handleMatrix is defined in the attachment.
a =
15 1
w=[a,6 7 8]
w =
15 1 6 7 8
a(1)=10;
w
w =
10 1 6 7 8
