ClassDescriptionAn implementation of
RealEigenDecomposition, which merely wraps an instance ofEigenDecompositionas provided by the Apache Commons Math library.Eigenvalues and eigenvectors of a real matrix.Implements an efficient, closed form algorithm for calculating the real eigenvalues (λ) and eigenvectors (x) of a 2x2 matrix of the formSolves the generalized eigenproblem of the form A x = λ B x, for square matrices A, B.Solves the generalized symmetric eigenproblem of the form A x = λ B x, where matrices A, B are symmetric and B is positive definite (see Sec.Common interface for eigendecompositions capable of delivering solutions when all eigenvalues are real.
