1function [pos, E] = bp_chain(n, len)

2% BP_CHAIN A straight line of n beads along x, from 0 to len.

3% [pos, E] = bp_chain(n, len) returns positions (n-by-3) and the n-1

4% neighbor pairs E. The end beads are 1 and n.

5x = linspace(0, len, n)';

6pos = [x, zeros(n, 2)];

7E = [(1:n-1)', (2:n)'];
