Ran in:
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

Ran in:
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
