Hi;
I have a matrix that first column shows the tasks, second column is the station numbers that tasks assigned and third one is the total station times as:
ST= [ 1 1 6
5 1 10
4 2 5
2 2 7
3 3 9
7 4 6]
I want to have the each station's last total station time as it should be =[10 7 9 6].
How can I write it's code?
Thanks in advance; Regards...

arrayfun(@(x) ST(find(ST(:,2)==x, 1, 'last'), 3), unique(ST(:,2)))
