Detailed Description

template<typename T>
class libMesh::DenseVector< T >

Defines a dense vector for use in Finite Element-type computations.

This class is to basically compliment the DenseMatrix class. It has additional capabilities over the std::vector that make it useful for finite elements, particularly for systems of equations. All overridden virtual functions are documented in dense_vector_base.h.
