I am also interested in large matrices, and particularly on sparse large matrices that still take up ~ 100GB despite being sparse (!)

Has anyone used this algorithm with large matrices?
It seems to be extremely fast for small matrices, but on matrices on the order of gigabytes I get much slower results than simpler methods.

A comment regarding Bakshi's comment (above), asking for dmperm: see the "CSparse" package, also on MATLAB Central. That package also includes various sparse factorization (LU, Cholesky, and QR). They're written in C, and not provided as M-files, however.

So far, I've only used the Visualization .m's. They're most useful and complement some of the features of EigTool which isn't accessible to those without Matlab.

On a purely selfish basis, I'd like to see the inclusion in the Factorizations and Decompositions .m's, the Dulmage - Mendelsohn decomposition for sparse arrays, mainly because the Matlab built-in dmperm is rather opaque and the FORTRAN 77 code on which it's based is not readily available.

Many thanks, a useful contribution.
