Deleting rows based on the entries of first row

Hi all, I am working with text files and there are duplicate entries in the first column which stands for time. After loading, i am using 'unique' command on this column but when the same is applied on the other columns i get different length because of the entries. Is there any command that finds duplicate entries in first columns and then removes the whole row particularly for text files Best Regards, Fawad Maqbool

 [~, uidx] = unique(YourArray(:,1));
 NewArray = YourArray(uidx, :);
