Minkowski distance

The Minkowski distances are the set of distance metrics with different degree LaTex Math image. and are widely used for distance computation in different algorithms. The most commonly used distance metric, Euclidean distance, is also a Minkowski distance with LaTex Math image..

Template Parameters
  • Float
     – The floating-point type that the algorithm uses for intermediate computations. Can be
    float
     or
    double
    .
  • Method
     – Tag-type that specifies an the implementation of the algorithm. Can be
    method::dense
    .
  • Task
     – Tag-type that specifies the type of the problem to solve. Can be
    task::compute
    .
