remove rows with duplicates

Show older comments
Consider a following spreadsheet
Column 1 2 3
10 10 10
11 10 9
11 10 10
In this setting I want to delete Row 2 and Row 3 because they have duplicates in Column 1.
More generally, the problem is "I would like to delete any row that has a duplicate in Column 1." Please advise how to proceed

need_to_delete = [false; any(ismember(YourArray(2:end,:), YourArray(1,:)),2)];
YourArray(need_to_delete, :) = [];
