Subject Re: [Math] SingularValueDecomposition test case
Date Sun, 02 Oct 2005 06:11:18 GMT
Never having used or even learned anything in detail about SVD, my only
suggestion is that equations 2.6.1 and 2.6.4 in
http://library.lanl.gov/numerical/bookcpdf/c2-6.pdf are, as the text therein
says, the only defining requirements for the SVD of any matrix.  You could, as
the text says, verify that the calculated SVD is correct by making up any
matrix and checking whether the two above equations hold for the SVD you get
out of your code.
