Documentation

A ProfileSPDLinDirectSolver object can be constructed to solve a ProfileSPDLinSOE object. It does this by direct means, using the LDL^t variation of the cholesky factorization. The matrx A is factored one column at a time using a left-looking approach. No BLAS or LAPACK routines are called for the factorization or subsequent substitution.

A unique class tag (defined in <classTags.h>) is passed to the ProfileSPDLinSolver constructor.
