Subject: Errors in JAMA


Dear sir/madam,

  I am a research student working on Latent Semantic Index in which I
am using JAMA for single value decomposition. Additionally i am using
online BlueBit Matrix Calculator.
(http://www.bluebit.gr/matrix-calculator/calculate.aspx)

       for the input matrix:
1.000 2.000 1.000
2.000 3.000 4.000
3.000 4.000 2.000
5.000 6.000 7.000

I observed that, the signs of the values (positive and negative
values) in the matrices U and V values different.

Could u provide me the information regarding why it is happening.
