[2] We begin with the properties that are immediate consequences of the definition as a power series: e0 = I exp (XT) = (exp X)T, where XT denotes the transpose of X. exp (X∗) = (exp X)∗, where X∗ denotes the conjugate transpose of X. If Y is invertible then eYXY−1 = YeXY−1.

WebApr 10, 2024 · Particularly, graph G allows self-loop with diagonal entries of A set to 1, i.e., a i i = 1. The Laplacian matrix of graph G is defined as L = D − A, where D ∈ R n × n is the degree matrix with diagonal entries d i i = ∑ j a i j. The normalized version is given by L = I n − D − 1 2 A D − 1 2, where I n is the identity matrix. Webq, the complexity scales as the third power of the problem size. If only the distribution of the degree of statical indeterminacy in the structure is required, the calculation can be performed only for the main-diagonal entries of the redundancy matrix (7).
