checkForEigenvaluesAndEigenvectors

public static boolean checkForEigenvaluesAndEigenvectors()

Checks for the correctness of the Eigenvector and Eigenvalues calculation. The test relies on the X V = V E equation (Henrion^2 (1995),p219). X is the symmetric original matrix. V is the diagonal matrix of the eigenvalues and E is the matrix of the corresponding eigenvectors.

Returns:

true if the check is ok.
