Template Parameters
  • Float
     – The floating-point type that the algorithm uses for intermediate computations. Can be
    float
     or
    double
    .
  • Method
     – Tag-type that specifies 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
    .
Constructors
descriptor
() = default
Creates a new instance of the class with the default property values.
Method tags
struct
dense
using
by_default
 = dense
Alias tag-type for the dense method.
Task tags
struct
compute
Tag-type that parameterizes entities that are used to compute distances.
using
by_default
 = compute
Alias tag-type for the compute task.
