Yes, in CCS format, that's what the sparse() function does.

Your matrix will be inverted using a Cholesky factorisation, but if
you want to do it in slow motion yourself for pedagogical purposes,
you can do "chol" to see what the intermediate factorisation looks
like, and most importantly, how it preserves the sparsity.
