  \class SOPHYA::TMatrix
  \ingroup TArray
  
  The TMatrix class specializes the TArray class for representing
  two dimensional arrays as matrices. Matrix and vector operations,
  such as matrix multiplication or transposition is implemented.
  \b Matrix is a typedef for double precision floating point matrix ( TMatrix<r_8> ).

  \sa SOPHYA::TArray  SOPHYA::TVector
  \sa SOPHYA::Range  \sa SOPHYA::Sequence
  \sa SOPHYA::MathArray  \sa SOPHYA::SimpleMatrixOperation

  The following sample code illustrates vector-matrix multiplication 
  and matrix inversion, using simple gauss inversion.
  \code
  #include "array.h"
  // ....
  int n = 5;      // Size of matrix and vectors here
  Matrix a(n,n);  
  a = RandomSequence(RandomSequence::Gaussian, 0., 2.5);
  Vector x(n);
  x = RegularSequence(1.,3.);
  Vector b = a*x;
  cout << " ----- Vector x = \n " << x << endl;
  cout << " ----- Vector b = a*x = \n " << b << endl;
  SimpleMatrixOperation<r_8> smo;
  Matrix inva = smo.Inverse(a);
  cout << " ----- Matrix Inverse(a) = \n " << inva << endl;
  cout << " ----- Matrix a*Inverse(a) = \n " << inva*a << endl;
  cout << " ----- Matrix Inverse(a)*b (=Inv(a)*a*x) = \n " << inva*b << endl;
  cout << " ----- Matrix x-Inverse(a)*b = (=0 ?)\n " << x-inva*b << endl;
