say like I have this 2D matrix
11 2 3 6
5 6 9 8
9 55 11 12
80 14 15 16
17 97 35 20
21 22 23 27
and I want to find the 4 largest values in column 3. How do I do that? *I did read some of the other posts but I can't seem to find anything conclusive.

dvals = sort(YourMatrix(:,3), 'descend');
largest4 = dvals(1:4);

What should be done if there are duplicate matches? Five all the same, or one max and four copies of second best, or one max and one second best and three copies of the third best, and so on? Your question contains no information about how you want to handle ties.
