pmedian(data, ncenters)

Arguments

• data::Matrix: Coordinates of locations
• ncenters::Int: Number of centers

Description

The function calculates Euclidean distances between all possible rows of the matrix data. ncenters locations are then selected that minimizes the total distances to the nearest rows.

Output

• PMedianResult: PMedianResult object.

Example

julia> data1 = rand(10, 2);

julia> data2 = rand(10, 2) .+ 50;

julia> data3 = rand(10, 2) .+ 100;

julia> data = vcat(data1, data2, data3);

julia> result = pmedian(data, 3);
