Detailed Description

template<typename T>
class WMatrixSym< T >

Symmetric square matrix, storing only the elements of the triangular matrix without the main diagonal.

So in case of a NxN matrix there are only (N^2-N)/2 elements stored.

Notes:

There exists also a WWriter and WReader for storing/reading the matrix in VTK file format.

Member Function Documentation

template<typename T >

const std::vector< T > & WMatrixSym< T >::getData ( ) const

inline

Returns the elements stored inside of this container.

Returns

Read-only reference to the elements stored inside this container.

Definition at line 312 of file WMatrixSym.h.

template<typename T >

size_t WMatrixSym< T >::numElements ( ) const

inline

Returns the number of elements stored in this matrix.

Returns

the number of elements stored in this matrix.

Definition at line 300 of file WMatrixSym.h.

template<typename T >

T & WMatrixSym< T >::operator() ( size_t  i, size_t  j  ) throw ( WOutOfBounds )

inline

Element acces operator as if the elements where stored as a normal matrix.

Warning

Acessing elements of the main diagonal is forbidden!

Parameters

i	The i'th row
j	The j'th column

Returns

reference to the (i,j) element of the table

Definition at line 175 of file WMatrixSym.h.

template<typename T >

const T & WMatrixSym< T >::operator() ( size_t  i, size_t  j  ) const throw ( WOutOfBounds )

inline

Const version of the element access.

Warning

Acessing elements of the main diagonal is forbidden!

Parameters

i	The i'th row
j	The j'th column

Returns

Const reference to the (i,j) element of the table

Definition at line 158 of file WMatrixSym.h.

template<typename T >

void WMatrixSym< T >::setData ( const std::vector< T > &  data ) throw ( WOutOfBounds )

inline

Resets the internal data to the given vector of elements.

Parameters

data	new data in row major arrangement

template<typename T >

size_t WMatrixSym< T >::size ( ) const

inline

Returns the number of rows and cols of the matrix.

Returns

The number of rows and cols of the matrix.

Definition at line 306 of file WMatrixSym.h.

template<typename T >

std::string WMatrixSym< T >::toString ( void  ) const

inline

Renders the matrix to a full nxn matrix, where the main diagonal is set to 0.0 and the m(i,j) == m(j,i).

Each column is separated by exactly one space and each row is separated by a newline.

Returns

Multiline string containing the nxn symmetric matrix.
