Deleting Duplicates from 2 data sets

Hello dear members,

I was wondering, how can I smartly combine 2 data files and then delete values completely which are common like In fact I want to get Data-1-Data-2 this will remove the entries of data file 2 from data file 1.

Data-1

24/25/W3  23.1  56.3
24/25/W4  25.8  56.8
24/25/W5  29.6  57.9
24/25/W6  25.2  58.4
24/25/W7  25.96  55.7
24/25/W8  30  58

and Data-2

24/25/W5  25.8  56.8
24/25/W3  23.1  56.3
24/25/W10  30  58
24/25/W6  25.2  58.4
24/25/W8  30  58

I want an output file which have both data1 and data 2 entries but no dublicates. You can see there are few same values in above example. Thanks

data=unique([data_1;data_2],'rows')

Thanks Azzi,

But I'm interested to remove data which is present in data-2 from data 1. Unique will still keep one value of data-2 entries.. Lets say I have a = [1 2 3 4 5] b = [1 3 2] I want out put so out = [4 5]

[Azzi Abdelmalek]

a = [1 2 3 4 5]
b = [1 3 2] 
c=setdiff(a,b)

Thanks Azzi, But again I have a text file I just want to remove data from file-1 which is present in file-2. file-1 is composite data. tahnks
