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

在 MATLAB Online 中打开

handleMatrix.m

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
