Factorization¶
Upon successful completion of the factorization, a lower-triangular (with unit diagonal) \(L\) and diagonal matrix \(D\),
such that \(A = L D L^H\) or \(A = L D L^T\), will be returned in the
lower triangle of \(A\).
If a zero pivot is attempted, then a ZeroPivotException will
be thrown.
Python API¶
Elemental’s Python interface to unpivoted dense LDL factorizations can be
called as a special case of the pivoted interface, LDL() by
specifying pivType to LDL_WITHOUT_PIVOTING.
