Re: [eigen] 3.2.0-beta1 released!

[Sameer Agarwal <sameeragarwal@xxxxxxxxxx>]

Hi Gael,

This is really awesome work and I am extremely excited to see Eigen have such robust support for sparse matrices.  I am hoping to add Eigen based sparse matrix support in Ceres Solver, so that we can reduce our dependencies for large scale solves down to just Eigen and glog if needed.

So, at the risk of sounding like an ingratiate I have a few questions.

1. I noticed that while the SparseLU and SparseQR modules are MPL2 compatible, SparseCholesky is not. Is there any hope/plan to have a MPL2 compatible sparse cholesky factorization in Eigen?

2. Are these factorizations threaded? if not are there any plans on adding threading support.

Thanks,

Sameer

Hi,

I'm pleased to announce that Eigen 3.2.0-beta1 has been released
today, on March 7, 2013.

The source archive is at: http://bitbucket.org/eigen/eigen/get/3.2-beta1.tar.bz2

This beta version introduces built-in LU and QR factorizations for
sparse matrices, a real-QZ factorization and a generalized eigen
solver for dense matrices, a new Ref<> class to ease writing generic
but non-template functions taking Eigen objects as arguments, wrappers
to the Metis and SuiteSparse QR libraries, as well as a couple of
minor enhancements and bug fixes.

Complete changelog:

cheers,
Gael
