[Comment] Consult on StructuredMatrix factor

[AlexGKim]

I would appreciate some insight on the proper use of STRUMPACK. I have a symmetric matrix C for which I would like to compute

o^T C^{-1} o and log (det(C))

With DenseMatrix this can be calculated in an efficient way using Cholesky by determining L^{-1}o and summing the determinant of the diagonal of L.

Looking at the API and examples, it was not clear how to use StructoredMatrix::factor() to accomplish the same thing.

I am using small matrices in preliminary testing but our real problem requires large matrices in distributed memory.

I would appreciate insight on how to proceed. Thanks!
