If the eigenspace ...In such cases, the eigenvalue \(3\) is a degenerate eigenvalue of \(B\text{,}\) since there are two independent eigenvectors of \(B\) with eigenvalue \(3\text{.}\) Degenerate eigenvalues are also referred to as repeated eigenvalues. In this case, one also says that \(3\) is a repeated eigenvalue of multiplicity \(2\).Repeated Eigenvalues We continue to consider homogeneous linear systems with constant coefficients: x′ = Ax is an n × n matrix with constant entries Now, we consider the case, when some of the eigenvalues are repeated. We will only consider double eigenvalues Two Cases of a double eigenvalue Consider the system (1).eigenvalue of L(see Section 1.1) will be a repeated eigenvalue of magnitude 1 with mul-tiplicity equal to the number of groups C. This implies one could estimate Cby counting the number of eigenvalues equaling 1. Examining the eigenvalues of our locally scaled matrix, corresponding to clean data-sets,The eigenvalues, each repeated according to its multiplicity. The eigenvalues are not necessarily ordered. The resulting array will be of complex type, unless the imaginary part is zero in which case it will be cast to a real type. When a is real the resulting eigenvalues will be real (0 imaginary part) or occur in conjugate pairs The line over a repeating decimal is called a vinculum.
