MATLAB: How to create a matrix (64 X 6) with all numbers from 1 to 64, written by binary code

Question

I try to use this function , but I have just a matrix(64 X 1)

D = [ ];
D = str2num(dec2bin(0:63, 6));

The solution must be :

D = [ 0 0 0 0 0 0
      0 0 0 0 1 0
      0 0 0 0 1 1
      0 0 0 1 0 0
      .................
      1 1 1 1 1 1]

Answer 1

D=double(dec2bin(0:63,6))-'0';
