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

A = [5;0;0;4;3;0];
[cnt,idx] = histc(A,unique(A));
[~,idz] = max(cnt);
B = idx==idz;
outputs this
>> B
B =
0
1
1
0
0
1
and A = [1;1;0;4;3;1]; outputs this:
>> B
B =
1
1
0

Many thanks Walter Roberson.
I am not looking for the min. or max. values in the matrix.
I want to find rows which has the most frequent number. for instance in example 2, rows with number "1" are repeated three times. Therefore, I want to replace these rows with "1". However, in this example the numbers are already 1. Afterward, I want to replace 0 in other rows.
Thank you for the cooperation.

What you ask and the example you show are not consistent. To produce what you show:
B = A == 0

Many thanks José-Luis. Please see my comment for Walter Roberson.
If you look at the following example, 2 is the most frequent number in the matrix, so, I want to replace this number with 1. Afterward, I want to replace 0 in the other rows.
A=
2
2
0
4
3
2
B=
