void _cholesky_back_substitute(const DenseVector< T2 > &b, DenseVector< T2 > &x) const
Solves the equation Ax=b for the unknown value x and rhs b based on the Cholesky factorization of A.
The libMesh namespace provides an interface to certain functionality in the library.
void vector_mult(DenseVector< T > &dest, const DenseVector< T > &arg) const
Performs the matrix-vector multiplication, dest := (*this) * arg.
void vector_mult_transpose(DenseVector< T > &dest, const DenseVector< T > &arg) const
Performs the matrix-vector multiplication, dest := (*this)^T * arg.
