Problem with making a matrix of size [2 2 4 2] , need help

if true
  % I want to make a matrix of this size( 2     2     4     2) from this following data set
Data = [12.2537   13.4153
 10.3552   12.3899
  9.5644   12.1267
  0.8660    0.5590
  4.4718    5.1405
  4.1300    3.7492
  4.0248    3.0958
  0.5590    0.5000
  6.9277    6.9114
  6.2339    6.2827
  6.0672    6.1021

 12.5654    4.3318
 12.2043    4.1110
  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
      end
  end
end

and I want to allocate this to A_int, I have tried something like that but it doesn't work Can somebody help me in this please Regards, 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.

brilliant thanks alot , even I know I am doing it wrong but i couldn't able to figure it out how can I make a matrix of [2 2 4 2] out of 16 x 2 array.

[John D'Errico]

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.

Answer 2

[Harshvardhan]

reshape(Data, [2 2 4 2])

Does that do that job for you?

[Nasir Qazi]

yes that does it all cheers for that bud

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