sym_mat | A sparse cholesky solver | Jon Wilkening |
I wrote this code when I was in grad school and became interested in learning how to store and manipulate sparse matrices. I have used it frequently since 1999 to solve fairly large systems (with around 100,000 unknowns) arising from 2d finite element stiffness matrices in fluid and solid mechanics.
