Sparse Schur Complement is Computed Wrong

Havlu

Hi,

I am trying to use pardiso to compute the Schur complement of a matrix. I had some stability issues for some large matrices, so I decided to put in a tiny matrix and see if I can figure out the issue. However, it looks like for the small matrix I have, the Schur complement is computed wrong.

This matrix is real symmetric and 8-by-8. The code is attached and it is commented for ease of reading. Any help is appreciated.

Thank you,
Abdullah
