Prev: Mean of nonzero elements in a 2D Array w/o a loop?

Hi still unfortunately i am having problems selecting characters from file names due to the fact that the stock ID's are between 2 and for characters long, for example..

TESCO_20081225
AB_20060914
AAL_20070914

I want to get a vector of stock ID's and a vector of dates.

my code so far is as follows;

clear;
rootDir = 'C:\Users\Desltop\Dissertation Data\lse

tmp = dir([rootDir '*.csv']);
fnames = char({tmp.name}');
clear tmp;

If the stock ID's had all been of equal length, i.e. 3 characters i know i could have used;

stockIDs = unique(cellstr(fnames(:1:3)));

But because they are not this does not give the required result.

Please could someone (give constructive) advice how to solve this problem. Please note i am a very new user to matlab so please keep sarcastic comments to yourself.

Many thanks
Alex
