create all logic permutation array

how cloud i create all random logic array when the length is known

eg: length=3
arr=[ 1 0 0
         0 1 0
         0 0 1
         1 1 0
         0 1 1
         1 0 1
         1 1 1]

d = (1:2.^3-1)';
b = de2bi(d);
b

b = 7×3

1 0 0 0 1 0 1 1 0 0 0 1 1 0 1 0 1 1 1 1 1

If you don't have the communications toolbox:

n = 3; % number of bits

LUT = dec2bin((0:2^n-1).',3)=='1'

LUT = 8×3 logical array
   0   0   0
   0   0   1
   0   1   0
   0   1   1
   1   0   0
   1   0   1
   1   1   0
   1   1   1

Note the bit order. Also, this example includes 0
