TMatrixTSym< Element > Class Template Reference

template<class Element>
class TMatrixTSym< Element >

TMatrixTSym.

Template class of a symmetric matrix in the linear algebra package.

See the Matrix Linear Algebra page for the documentation of the linear algebra package

Note that in this implementation both matrix element m[i][j] and m[j][i] are updated and stored in memory . However, when making the object persistent only the upper right triangle is stored .
