I have a matrix that is nx3, and am trying to do the following with it: 1) For each row, sort its three entries from smallest to largest. 2) Order the rows from smallest to greatest by the first entry (using the sortrows function). 3) Check for repeated rows in the matrix. If the row of three numbers appears more than once, I would like to delete all of its appearances from the matrix. In the end, the output should be a matrix containing all rows that only appeared once in the original.
Any help would be appreciated with this. Thank you!
