The eigenVectorsEquality
threshold is used to ensure the L∞-normalized
eigenvectors found using inverse iteration are different from each other.
if \(min(|e_i-e_j|,|e_i+e_j|)\) is smaller than this threshold, the algorithm
considers it has found again an already known vector, so it drops it and attempts
a new inverse iteration with a different start vector. This value should be
much larger than epsilon
which is used for convergence
