data=
[1 1 1 2 2 12;
2 18 5 5 5 5;
5 1 1 5 5 5;
4 11 13 2 2 12;
5 1 1 5 5 5]
... (2093 lines)
mode = [5 1 1 5 5 5]
I found a way to find the mode row. In this preview, it's [5 1 1 5 5 5]. How do I remove such rows from the matrix?

data( idx, : ) = [];
will delete a row (or multiple rows), idx, from a matrix. Since you say you already have a way to find the row you want I assume this is all you are asking?

@Tudor, since uA is a column vector, uA(modeIdx, :) is the same as ua(modeIdx), and since modeIdx is scalar, ua(ModeIdx, :) is scalar. So modeRow is scalar, so it's totally expected that only one row is removed.
modeRow = uIdx == modeIdx;
would fix your problem.
