static void copy(const coeff_type &x, coeff_type *y)
Copy a coefficient.
Thyra::VectorBase< Scalar > coeff_type
Typename of coefficients.
static void update(coeff_type *y, const coeff_type &x, const scalar_type &beta)
y = x + beta*y
static Teuchos::RCP< coeff_type > clone(const coeff_type &c)
Clone a coefficient.
static void assign(coeff_type *y, const scalar_type &alpha)
Assign a scalar to a coefficient.
Abstract interface for finite-dimensional dense vectors.
virtual RCP< VectorBase< Scalar > > clone_v() const =0
Returns a seprate cloned copy of *this vector with the same values but different storage.
