Sort elements from multidimensional array into 2D array?

So I have a Multidimensional array S (115 x 90 x 64) and I need to form multple 64x1 arrays B. So for example, the first B is the first element in the 64 115x90 S array S(1,1,:). How would I go about doing this?

So, you want to pick only diagonale elements? What should be second column of B?

Sorry for the confusion, what im trying to achieve is basically this:

i = 1:64

B1 = S(1,1,i)
B2 = S(2,1,i)
B3 = S(3,1,i)
.
.
.
Bn = S(115,90,i)

resulting in many B 64x1 arrays

So, we need a way to extract the 2D matrix along z-axis and then save them separately.

Refer the following link for similar query and you can follow up the solution provided there.

Instead of saving it in different .csv files, you can store them simply in a 2D array.

S = rand(115, 90, 64) ;
B = squeeze(S(:,1,:)) ;
whos B

  Name        Size            Bytes  Class     Attributes

  B         115x64            58880  double

So there are 64 arrays composed of 115x90 elements, i need each element in every array stored into a different 64x1 array so i should end up with 115x90 B arrays composed of 64x1 elements.

[KSSV]

S = rand(115, 90, 64) ;
iwant = cell(115,90) ;
for i = 1:115
    for j = 1:90
        iwant{i,j} = squeeze(S(i,j,:)) ; 
    end
end

yep that's done it, cheers
