inline

Copy the vector.

Parameters

v	vector to copy

Definition at line 393 of file Vector_eigen.hpp.

operator=() [2/3]

template<typename T >

Vector<T>& Vector< T, EIGEN_BASE >::operator= ( const Vector< T > &  v )

inline

Copy the vector.

Parameters

v	vector to copy

Definition at line 378 of file Vector_eigen.hpp.

operator=() [3/3]

template<typename T >

Vector<T>& Vector< T, EIGEN_BASE >::operator= ( Eigen::Matrix< T, Eigen::Dynamic, 1 > &  v )

inline

Copy the vector (it is used for special purpose)

Warning

v MUST contain at least all the elements of the vector

Parameters

v	base eigen vector to copy

Definition at line 410 of file Vector_eigen.hpp.

resize()

template<typename T >

void Vector< T, EIGEN_BASE >::resize ( size_t  row, size_t  l_row  )

inline

Resize the Vector.

Parameters

row	numbers of row
l_row	unused

Definition at line 206 of file Vector_eigen.hpp.

scatter()

template<typename T >

void Vector< T, EIGEN_BASE >::scatter ( )

inline

Scatter the vector information to the other processors.

Eigen does not have a real parallel vector, so in order to work we have to scatter the vector from one processor to the other
