For matrix 210x2x4 I want to generate a 840×2 matrix, where in this order:

    [matrix(1,:,1);matrix(1,:,2);matrix(1,:,3);matrix(1,:,4);matrix(2,:,1);matrix(2,:,2);....]

I'm still not clear how to insert values between values in matrices, any suggestions?

MATLAB: Generating an “all-combinations” matrix for a given vector

x = [2 3 4];
n = prod(x);
for i = 1:numel(x)
  li = []; for ii = 1:x(i), li = [li repmat(ii, [1 n/prod(x(1:i))])]; end, 
  A(i,:) = repmat(li, [1 n/numel(li)]);
end

% Let X - your data with size  (60x100x40000)
% ii - your vector with index of columns X from each frame of X (1x46000)
[m,n,k] = size(X);
x1 = reshape(X,m,[]);
x2 = x1(:,n*(0:k-1)+ii(1:k));
