Detailed Description

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

This class defines a vector in LIBMESH_DIM dimensional Real or Complex space. The typedef RealVectorValue always defines a real-valued vector, and NumberVectorValue defines a real or complex-valued vector depending on how the library was configured.

Constructor & Destructor Documentation

◆ VectorValue() [1/7]

template<typename T >
libMesh::VectorValue< T >::VectorValue ( )
inline

Empty constructor. Gives the vector 0 in LIBMESH_DIM dimensional T space.

Definition at line 139 of file vector_value.h.

139  :
140  TypeVector<T> ()
141 {
142 }

◆ VectorValue() [2/7]

template<typename T>
libMesh::VectorValue< T >::VectorValue ( const T  x,
const T  y = 0,
const T  z = 0 
)
inline

Constructor-from-T. By default sets higher dimensional entries to 0.

Definition at line 147 of file vector_value.h.

149  :
150  TypeVector<T> (x,y,z)
151 {
152 }

◆ VectorValue() [3/7]

template<typename T >
template<typename Scalar1 , typename Scalar2 , typename Scalar3 >
libMesh::VectorValue< T >::VectorValue ( typename boostcopy::enable_if_c< ScalarTraits< Scalar1 >::value, const Scalar1 >::type  x,

typename boostcopy::enable_if_c< ScalarTraits< Scalar3 >::value, const Scalar3 >::type  z = 0 
)
inline

Constructor-from-scalars. By default sets higher dimensional entries to 0.

Definition at line 159 of file vector_value.h.

167  :
168  TypeVector<T> (x,y,z)
169 {

template<typename Scalar >
libMesh::VectorValue< T >::VectorValue ( const Scalar  x,
typename boostcopy::enable_if_c< ScalarTraits< Scalar >::value, const Scalar >::type *  sfinae = nullptr 
)
inline

Constructor-from-scalar. Sets higher dimensional entries to 0. Necessary because for some reason the constructor-from-scalars alone is insufficient to let the compiler figure out VectorValue<Complex> v = 0;
