for example 4x2 matrix, the output should be [1 0;1 1;0 1; 0 0]. In this matrix no rows are repeated. I uses the code randi([0,1],4,2). I got 4x2 matrix but getting repeated row like [1 0;1 1;1 0; 0 0].Here, row1 and row3 are same, which is not acceptable.
please help to construct the matrix without any repeation of rows.

One of ways:
dec2bin(0:3)-'0'

result = dec2bin(randperm(4)-1) - '0';
