Reshape multidimensional arrays - interpretation

Hi,

I have a 5D array (X) with the following variables: A, B, C, D and E each having lengths 10, 4, 2, 1000 and 20.

I have reshaped X as following: X2 = reshape(X,[],1000,20). When I run size(X2), I get 80 1000 20, which I understand. However, when I plot X2(1,:,1) how should the plot be interpret? Is X2(1,:,1) equal to (A1,B1,C1) and X2(2,:,1) equal to (A2,B1,C1) or am I wrong?

Thanks!

Second column of first plane: same except with D2 instead of D1.

Third column of first plane: same except with D3 instead of D1

So the first row of the first plane has A1B1C1D1E1 A1B1C1D2E1 A1B1C1D3E1 ... A1B1C1D1000E1

Second row of the first plane has A2B1C1D1E1 A2B1C1D2E1 A2B1C1D3E1 ... A2B1C1D1000E1

which does not disagree with what you wrote.
