9.5644 12.1267
0.8660 0.5590

0.4146 0.4330]
for i=1:2
for j=1:2
for k=1:4
for m=1:2
A_int(i,j,k,m) = Data(i,j,k,m)
end

It is time to learn how to use reshape.
help reshape
As importantly, you need to understand that you cannot index an 8x2 array with four indexes as you have tried. MATLAB cannot read your mind.

Never copy numbers like this with loops.
reshape(A,[2 2 4 2])
If the numbers are not in the order you wanted, then learn to use permute.

Data is a 16 x 2 matrix, so Data(i,j,k,m) is wrong.
