[PDF] euclidean distance matrix

  • What is the Euclidean distance matrix?

    Euclidean distance matrices (EDM) are matrices of squared distances between points.
    The definition is deceivingly simple: thanks to their many useful properties they have found applications in psychometrics, crystallography, machine learning, wireless sensor networks, acoustics, and more.

  • What is the Euclidean distance matrix problem?

    A Euclidean distance matrix (EDM) is one in which the (i, j) entry specifies the squared distance between particle i and particle j.
    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 an EDM.

  • What is the Euclidean form of a matrix?

    The Euclidean norm of a square matrix is the square root of the sum of all the squares of the elements.

  • What is the Euclidean form of a matrix?

    The Euclidean distance matrix is an n-by-n matrix whose entries are given by the squared distance between each pair of points (x,y,z).
    The Gram matrix is simply the matrix of inner products.
    So if X is a 3-by-n matrix whose columns are the points, then the Gram matrix is given by X^T@X.
