It looks like there should be a Project.toml in this folder.

Do you need ldl() or is cholesly() sufficient for the example?

cholesky() is sufficient but you need to allocate a new vector at each iteration when systems with sparse M and N are solved because lmul! is not implemented for SuiteSparse.CHOLMOD structure.

I give an example with both because of that.
