Diagonalize sparse matrix and documentation in version 6.

Dear Group,

I am currently writing code involving the diagonalization of large 
sparse matrix.  With a little research, I found this post on the group:
http://groups.google.com/group/comp.soft-sys.math.mathematica/browse_thread/thread/04e12cc442615ff1
explaining some very useful options (like Method -> {Arnoldi, 
MaxIterations -> 10^5,
Criteria -> RealPart}).
    However, I found no mention of these options in the documentation 
center of my Mathematica v6. The best I could find is this page on 
Wolfram site: 
http://documents.wolfram.com/v5/Built-inFunctions/AdvancedDocumentation/LinearAlgebra/4.4.html
but the page is for version 5.0 and called obsolete. I could not find an 
equivalent page for version 6.  Am I missing something, or are these 
options for eigensystems not documented in version 6.0 ?


Thanks for any help,


Thibaut Jonckheere
