[SciPy-user] Indefinite coefficient matrix

Hi all,

I wan't to solve a system of linear equations

A x = b,

where A is symmetric but indefinite. Thus one cannot use a Cholesky
factorization L L^T.
AFAIK one can use an L D L^T - factorization, where D is a diagonal matrix.
Is this factorization available in numpy/scipy ?
