I have a matrix with n rows and 1 column. I would like to find rows which has the maximum number of rows. Then, replace zero in the other rows.
For instance: I have matrix A and I would like to produce matrix B.
A=
5
2
2
4
3
2
B=
0

This works:
A = [5
2
2
4
3
2];
[Au,ia,ic] = unique(A, 'stable');
h = accumarray(ic, 1);
B = A;
B(ic~=Au(h==max(h))) = 0
B =
0
2
