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...
LIBMESH_VMA_INSTANTIATE(Real, int, Real)
The libMesh namespace provides an interface to certain functionality in the library.
void vector_mult_transpose(DenseVector< T > &dest, const DenseVector< T > &arg) const
Performs the matrix-vector multiplication, dest := (*this)^T * arg.
std::complex< Real > Complex
DIE A HORRIBLE DEATH HERE typedef LIBMESH_DEFAULT_SCALAR_TYPE Real
Defines a dense vector for use in Finite Element-type computations.
void cholesky_solve(const DenseVector< T2 > &b, DenseVector< T2 > &x)
For symmetric positive definite (SPD) matrices.
void vector_mult(DenseVector< T > &dest, const DenseVector< T > &arg) const
Performs the matrix-vector multiplication, dest := (*this) * arg.
