 math_Jacobi (const math_Matrix &A)
 Given a Real n X n matrix A, this constructor computes all its
eigenvalues and eigenvectors using the Jacobi method.
The exception NotSquare is raised if the matrix is not square.
No verification that the matrix A is really symmetric is done.

Standard_Boolean IsDone () const
 Returns true if the computations are successful, otherwise returns false.

const math_VectorValues () const
 Returns the eigenvalues vector.
Exception NotDone is raised if calculation is not done successfully.

Standard_Real Value (const Standard_Integer Num) const
 returns the eigenvalue number Num.
Eigenvalues are in the range (1..n).
Exception NotDone is raised if calculation is not done successfully.

const math_MatrixVectors () const
 returns the eigenvectors matrix.
Exception NotDone is raised if calculation is not done successfully.

void Vector (const Standard_Integer Num, math_Vector &V) const
 Returns the eigenvector V of number Num.
Eigenvectors are in the range (1..n).
Exception NotDone is raised if calculation is not done successfully.

void Dump (Standard_OStream &o) const
 Prints information on the current state of the object.
Is used to redefine the operator <<.
