How to find multiple duplicates in an array

Hi, i am a beginner in matlab and trying to write a code for my data, but got stuck in this bit. I have a list of names in one vector(varies in length on each loaded data set) and time in another. In this list of names that corresponds to the time, there are at least 9 duplicates of each name, that i want to find and group together into bins and refer to the correct timing.
Example: n = [a b c d e a a e c d a ...]
t = [10.01 2.1 5.01 6.07 9.3 10.02 10.0 9 5.05 6.1 10.001 ...]
how can i ask matlab (7.6) to group all the a together and their t values, then all the b, all the c, and etc.
Much appreciated for any help.

n = {'a' 'b' 'c' 'd' 'e' 'a' 'a' 'e' 'c' 'd' 'a'}
t = [10.01 2.1 5.01 6.07 9.3 10.02 10.0 9 5.05 6.1 10.001 ]
k=unique(n)
out=[k' cellfun(@(x) t(ismember(n,x)),k,'un',0)']
