Hello
I have a matrix like this:
1 2 3
4 5 6
7 8 9
Now, I want to transform it to this:
1
2
3
4
5
6
7
8
9
Note, the real values are not in row, so sort is no option.
Thanks in advance.

simply this :
>> a = [1 2 3 ;
4 5 6;
7 8 9];
>> a(:)
ans =
1
4
7
2
5
8
3

Thank you. I already tried this. But the ans should be:
ans =
1
2
3
4
5
6
7
8
9

I found a way. Maybe not beautiful but functional:
a =
1 2 3
4 5 6
7 8 9
iii = 1;
for i = 1:rows(a);
for ii = 1:columns(a);
b(iii,1) = a(i,ii);
iii++;
end;
end;
b =
1
2
3
4
5
6
7
8
9
