See <A HREF="../Mat/MatLUFactor.html#MatLUFactor">MatLUFactor</A>() for in-place factorization. See
<A HREF="../Mat/MatCholeskyFactorNumeric.html#MatCholeskyFactorNumeric">MatCholeskyFactorNumeric</A>() for the symmetric, positive definite case.
<P>
Most users should employ the simplified <A HREF="../KSP/KSP.html#KSP">KSP</A> interface for linear solvers
instead of working directly with matrix algebra routines such as this.
See, e.g., <A HREF="../KSP/KSPCreate.html#KSPCreate">KSPCreate</A>().
