remove duplicates from matrix and create a logic to index

i have a table with time and it contains some duplicated times. i would like to remove those duplicated times and then be able to use this to index into another matrix so i can find out what happens at that specific time that is not a duplicated time.

time = [1 2 2 3 4 4 5 6 6 7 8 ]'

data= is the same size as matrix as time;

i would like to remove those duplicated times and then index into data so at times [1 2 3 4 5 6 7 8].

REad about the function unique.

time = [1 2 2 3 4 4 5 6 6 7 8 ]' ;
[c,ia,ib] = unique(time) ; 
data = data(ia) ;
