adjacency_mat: Compute the adjacency matrix of the gaussian weighted graph

Description

Compute the adjacency matrix of the gaussian weighted graph

Usage

adjacency_mat(pts, f = function(x) {     exp(-x^2/8) }, s = 0)

Arguments

pts

coordinates of N points in \(R^3\).

f

is a scalar potential (\(\exp(-x^2/2t^2)\) for gaussian potential)

s

is a threhold to sparisfy the matrix

Examples

# NOT RUN {
pts <- swissroll(N=100, seed=0, a=1, b=4)
W <- adjacency_mat(pts)
# }
