causet_new_permuted.m

function coord = causet_new_permuted( permutation )
%CAUSET_NEW_PERMUTED creates a 1+1 dimensional causet from an permutation
% vector of integers. The permutation defines the lightlike v-coordinate,
% while the u-coordinate increases from 1 to the length of the permutation
% vector.
