Detailed Description

template<typename T>
class WMatrixSymImpl< 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.
