There was a problem hiding this comment.
It's not completely clear but the comment right above is the explanation for the zero so it is wrong to remove it here. Instead, I'd just split the method into one for matrices and one for vectors.

Thanks so much for the comment. I also wrote a test for the symmetric matrix case. |

In case this gets successfully rebased on master, I'd suggest #34989 (review). |

(\) for Factor and SparseVecOrMat has the following method error:
The method error is due to the call
Sparse(A::SparseMatrixCSC{Tv,SuiteSparse_long}, stype::Integer).It should call
Sparse(A::SparseVector{<:VTypes,SuiteSparse_long})andSparse(A::SparseMatrixCSC{<:VTypes,<:ITypes})instead.I fixed it and wrote a test:
