class TMatrixTSym<float>: public TMatrixTBase<float>


TMatrixTSym

Template class of a symmetric matrix in 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 .
