MSTDist {GeoRange}

Calculates the minimum spanning tree distance, in kilometers, using Prim's Algorithm [1]

Description

Calculates the minimum spanning tree distance, in kilometers, using Prim's Algorithm [1]

Usage

MSTDist(longs, lats)

Arguments

longs

- Longitudinal occurrences in decimal degrees

lats

- Latitudinal occurrences in decimal degrees

Details

Uses Prim's algorithm for finding the minimum spanning tree, time-consuming calculation as the number of locations increases past 1000

Value

Returns the minimum spanning tree distance in kilometers, the pairwise distance matrix of occurrences, the order points were connected in, and a 2-column array of coordinates
