TMatrixT<Element> &TMatrixT<Element> operator/=(const TMatrixTRow_const<Element> &row)
 Divide a matrix by the row of another matrix
 matrix(i,j) /= another(k,j) for fixed k
const TMatrixT<Element> TMatrixT<Element> EigenVectors(TVectorT<float>& eigenValues) const
 Return a matrix containing the eigen-vectors ordered by descending values
 of Re^2+Im^2 of the complex eigen-values .
 If the matrix is asymmetric, only the real part of the eigen-values is
 returned . For full functionality use TMatrixDEigen .
void TMatrixT<Element> Streamer(TBuffer& b)
 Stream an object of class TMatrixT.
