-------------------------------
Summary: errors in eigenValues and eigenVectors wiki page
Key: HAMA-882
URL: https://issues.apache.org/jira/browse/HAMA-882
Project: Hama
Issue Type: Documentation
Components: documentation
Reporter: lujing.zui
Priority: Trivial
In "EigenValues and EigenVectors" wiki page.
step 3 in methods
"each rotation just effects 4 elements of the matrix".
this is error. actully echo rotation effects two rows and two cols, matirx is
symmetric, so effects two rows.
4 elements is totally WRONG.
and the pseudocode described below, it's confusing.
c,s computed as this which is not metioned.
c = cos(\theta)
s = sin(\theta)
someone can improve this page, despite i know the JacobiEigenValue removed in
the repo?
