Lattice coding and decoding

function elems = grab(latt,elements)

%GRAB Grab desired lattice elements
%   P = GRAB(L,PATT) returns desired lattice elements specified via
%   pattern in PATT variable.
% 
%   Example:
%       pts = 2 ^ 4;
%       Z2 = makelatt('Z',pts,2);
%       patt = [1:3,5,6,12:16];
%       P = grab(Z2,patt);
%       showlatt(P,'Style',1); hold on;
%       showlatt(Z2,'Labeling','num'); 
% 
%   Gives the elements (1,2,3,5,6,12,13,14,15,16) of Z2 lattice.
