## Main Question or Discussion Point

I need to keep track of the size of the matrix myself.

This means I can't use "size" function.

Is it possible?

For example,

A is a 5 x 5 matrix. I need to create a vector x=[0,0,0,0,0].

It should be just

x = zeros(size(A,1),1); %or length(A)

but I need to check the size of A matrix without size function.

Could anyone give me hints?

Thank you
