eigenvalue of matrix

[lujing zui <lu...@gmail.com>]

I search jira, and find eigenvalue algorithm has been implemented in HAMA.
but I cannot find any module about it in code.
where I can find it?

Here's my old implementation using MapReduce and HBase table.

http://svn.apache.org/repos/asf/hama/branches/0.1/src/java/org/apache/hama/algebra/JacobiEigenValue.java

This algorithm repeatedly performs rotations until the diagonalization
is completed. In other words, each MapReduce job (one iteration of the
algorithm) performs a table full scan and updates in every iterations.
MapReduce framework was used to distribute the IO load, but I think
it's not good program.

If I have some time in the future, I'll introduce the BSP-based linear systems.

Thanks.
