class ProfileSPDLinDirectBlockSolver: public LinearSOESolver

A ProfileSPDLinDirectBlockSolver 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 block row at a time using a right-looking approach. No BLAS or LAPACK routines are called for the factorization or subsequent substitution.
