Hello,
Are there any plans to implement support for a permutation in QDLDL? It's often beneficial to precompute a sparsity-promoting ordering (e.g. with AMD or METIS) but it's costly to permute the matrix explicitly, especially when solving a sequence of systems. However, it should be possible to take the permutation into account while factorizing.
Thanks.
