iso_s_smooth

PURPOSE ^

function [Reg] = iso_s_smooth(simp,vtx,deg,w);

SYNOPSIS ^

function [Reg] = iso_s_smooth(simp,vtx,deg,w);

DESCRIPTION ^

function [Reg] = iso_s_smooth(simp,vtx,deg,w);

Calculates a second order discrete Gaussian smoothing operator of
degree = 1. See help iso_f_smooth for more details.



simp = The simplices matrix.
vtx  = The vertices matrix.
deg  = 1 for nodes, 2 for edges and 3 for faces
w    = smoothing weight, w=1...k, default value = 1
Reg  = The second order smoothing regulariser.
