How can I divide multiple matrices into individual arrays?

Good afternoon,

Sorry for bothering you, but I have encountered an issue when trying to separate multiple matrices into individual array. I have 8 matrices, each having a dimension of 500x500, and by wanting to store them separately I mean that there should be 250.000 arrays, each containing 8 values. For instance (using a smaller example):

A = [1, 2, 3; 4, 5, 6; 0 0 0]

B = [3, 2, 1; 6, 5, 4; 0 0 0]

The arrays should be like this:

array1 = [1, 3]

array2 = [2, 2]

array3 = [3, 1] and so forth.

The issue consists of, when using "for" loops, I cannot assign an index to an array, like in C++, for instance, having "array1", "array2" etc., but values being overwritten one over another. I would like, if you can help me in managing how to generate arrays regarding a variable, like so (I am referring at the example above, for better explaining the issue):

for k = 1:2;
    for i1 = drange(1:size(A, 1))
        for j1 = drange(1:size(A, 2))
            for i2 = drange(1:size(B, 1))
                for j2 = drange(1:size(B, 2))
                  v(k) = [A(i1, j1), B(i2, j2)];   %k is not dimension, or position
                end
            end
        end
    end
end

I would like "k" to be as an index, creating new arrays of dimension 2 at every iteration.

Thank you for your time and I am waiting for your suggestions!

Best regards,

A = [1, 2, 3; 4, 5, 6; 0 0 0];
B = [3, 2, 1; 6, 5, 4; 0 0 0];
out=arrayfun(@(x,y) [x,y],A,B,'un',0);
out=out(:);

Now you have 9 array inside the variable out, and you can access each row:

out{1}  % fist row
out{2}   % Second row
% And so on

Good afternoon,

Thank you very much for your reply! I have tried your solution and worked as intended for the large dimension matrices. I cannot express my gratitude enough for your help, sir! Believe me when I am saying that I have tried to solve this issue for about 3 hours before posting here. Once again, thank you very much!

Best regards,
