There is a popular “trick” for computing Euclidean Distance Matrices (although it’s perhaps more of an observation than a trick). The observation is that it is generally preferable to compute the second expression, rather than the first2.
uclidean distance matrices (EDMs) are matrices of the squared distances between points. The definition is deceivingly simple; thanks to their many useful proper-ties, they have found applications in psychometrics, crystallography, machine learning, wireless sensor net-works, acoustics, and more. Despite the usefulness of EDMs, they
22 sie 2015 · I need to calculate euclidean distance between two points in the fastest way possible. In C. My code is this and seems a little bit slow: float distance(int py, int px, int jy, int jx){. return sqrtf((float)((px)*(px)+(py)*(py))); } Thanks in advance. EDIT:
1.1 Background. Distance geometry and Euclidean distance matrices. Two foundational papers in the area of Euclidean distance matrices are [105] and [120]. The topic was further developed with the series of papers [63, 64, 65], followed by [43, 54].

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.
