DCReg: Decoupled Characterization for Efficient Degenerate LiDAR Registration

[ICML 2023] Official implementation of "A randomized schur complement based graph augmentor"

Julia interface with MUMPS sparse parallel direct solver

Form symmetric block matrices and condense them (eliminating blocks) at compile time using Schur complements. The goal is to manipulate KKT/augmented/saddle-point systems symbolically to obtain equivalent systems (typically: unsymmetric, symmetrized, and normal equations) that can be tackled by various numerical solvers
