select neighbors and find Top n in Matlab

If I have a matrix like this:
sample = [1 0.21852382 0.090085552 0.219984954 0.446286385
;0.21852382 1 0.104580323 0.138429617 0.169216538
;0.090085552 0.104580323 1 0.237582739 0.105637177;
0.219984954 0.138429617 0.237582739 1 0.192753169
;0.446286385 0.169216538 0.105637177 0.192753169 1]
I want to find the top ten max values in every rows in Matlab. what i do
in Matlab? and is it true? i want to find top-N method in select
neighbors.
