Random symmetric binary matrix

I want to make a symmetric (100x100) matrix with binary values and the numbers on the diagonal have to be 0. Can anyone help me?

See if this does what you want:

N = 6;                                          % Matrix Size
M = randi([0 1], N);
Mu = triu(M);
Ml = Mu';
Mout = Mu + Ml;
Mout = Mout - diag(diag(Mout))

I kept the matrix size small here so you can verify that it does what you want. Change it to 100 for your matrix.
