Hi again :) I developed some java program to calculate cosine similarity on the basis of TF*IDF. It worked very well. But there is one problem.... :(

for example: If I have following two matrix and I want to calculate cosine similarity it does not work as rows are not same in length

doc 1
1 2 3
4 5 6

doc 2
1 2 3 4 5 6
7 8 5 2 4 9

if rows and colums are same in length then my program works very well but it does not if rows and columns are not in same length.

Any tips ???
