I have this matrix :

Qx= 1
2 3
4 5 6
7 8 9 10
11 12 13 14 15

I want to put it in matrix format like this :

V= 1
2
3
4
.
.
.
14
15


what is the solution ?

V = Qx.'; % transpose
V = V(V~=0);

Don't! If there is a 0 somewhere in the lower part of Qx, the above will give unexpected result.

A better way is

V = Qx.';
V = V(triu(true(size(V))))
