Suppose we have an 3D-array r=ones(m,n,k). How to make a column of all the values of "r" in the following form? example,
for r=ones(2,2,2)
the desired table should look like:
A= [r(1,1,1),
r(2,1,1),
r(1,2,1),
r(2,2,1),
r(1,1,2),
r(2,1,2),
etc, ..] .
X-grid number changes first, then changes Y-grid number, and Z-grid number is "the weakest".

Using this test matrix we can show how to rearrange into a column:
>> r = reshape(1:8,2,2,2)
r =
ans(:,:,1) =
1 3
2 4
ans(:,:,2) =
5 7
6 8
you want either
>> r(:)
ans =
1
2
3
4
5
6
7
8
or
>> reshape(permute(r,[2,1,3]),[],1)
ans =
1
3
2
4
5
7
6
8
