HAR.TLineSeg: Uniformly sample from a max-plus tropical line segment

In TML: Tropical Geometry Tools for Machine Learning

Uniformly sample from a max-plus tropical line segment

Description

This function uses a hit-and-run sampler to uniformly sample from a max-plus tropical line segment

Usage

HAR.TLineSeg(D1, D2, tadd = max)

Arguments

D1	point in the tropical projective torus
D2	point in the tropical projective torus
tadd	string; max indicates max-plus addition, min indicates min-plus addition. Defaults to max

Value

point on the line segment defined by D1 and D2
