Norm estimates for inverses of Toeplitz distance matrices
j=1 yj φ(‖x − xj‖2), x ∈ R , where φ: [0,∞) → R is some given function, (yj) n 1 are real coefficients, and the centres (xj) n 1 are points in R. For a wide class of functions φ, it is known that the interpolation matrix A = (φ(‖xj − xk‖2)) n j,k=1 is invertible. Further, several recent papers have provided upper bounds on ‖A‖2, where the points (xj) n 1 satisfy the condition ‖xj − xk‖2 ≥ δ, j ...
متن کاملOn Euclidean distance matrices
If A is a real symmetric matrix and P is an orthogonal projection onto a hyperplane, then we derive a formula for the Moore-Penrose inverse of PAP . As an application, we obtain a formula for the MoorePenrose inverse of a Euclidean distance matrix (EDM) which generalizes formulae for the inverse of a EDM in the literature. To an invertible spherical EDM, we associate a Laplacian matrix (which w...
متن کاملAn algorithm for realizing Euclidean distance matrices
We present an efficient algorithm to find a realization of a (full) n × n squared Euclidean distance matrix in the smallest possible dimension. Most existing algorithms work in a given dimension: most of these can be transformed to an algorithm to find the minimum dimension, but gain a logarithmic factor of n in their worstcase running time. Our algorithm performs cubically in n (and linearly w...
متن کاملEuclidean Distance Matrices and Applications
Over the past decade, Euclidean distance matrices, or EDMs, have been receiving increased attention for two main reasons. The first reason is that the many applications of EDMs, such as molecular conformation in bioinformatics, dimensionality reduction in machine learning and statistics, and especially the problem of wireless sensor network localization, have all become very active areas of res...
متن کاملApplication of the Norm Estimates for Univalence of Analytic Functions
By using norm estimates of the pre-Schwarzian derivatives for certain family of analytic functions, we shall give simple sufficient conditions for univalence of analytic functions.
