  1. 29 mar 2014 · If you are looking for the most efficient way of computation - use SciPy's cdist() (or pdist() if you need just vector of pairwise distances instead of full distance matrix) as suggested in Tweakimp's comment.

  2. Books and survey papers containing a treatment of Euclidean distance matrices in-clude, for example, [31, 44, 87], and most recently [3]. The topic of rank mini-mization for Euclidean distance matrix problems is discussed in, for example, [34, 35, 55, 56, 99, 100].

  3. Distance matrices are a really useful tool that store pairwise information about how observations from a dataset relate to one another. Here, we will briefly go over how to implement a function in python that can be used to efficiently compute the pairwise distances for a set (s) of vectors.

  4. 3.1] A Euclidean distance matrix, an EDM in RN×N +, is an exhaustive table of distance-square dij between points taken by pair from a list of N points {xℓ, ℓ=1...N} in Rn; the squared metric, the measure of distance-square: dij = kxi − xjk 2 2, hxi − xj, xi − xji (1037)

  5. Given a partially-specified symmetric matrix A with zero diagonal, the Euclidean distance matrix completion problem (EDMCP) is to determine the unspecified entries to make A a Euclidean distance matrix. We survey three different approaches to solving the EDMCP.

  6. The nearest (or approximate) Euclidean distance matrix problem is to find a Euclidean distance matrix, EDM, that is nearest in the Frobenius norm to the matrix A, when the free variables are discounted. In this paper we introduce two algorithms: one for the exact completion problem and one for the approximate completion problem.
