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
