Truble codeing a diamond lattice

Hello, I have a problem with codeing a diamond lattice. I found a script for this porpouse that I would like to try but when I run it it says "error: 'diamondLattice' undefined near line 30, column 15". Is there somthing I need to change or add? Not really sure how to define the "diamondLattice". All help is vary much appreciated. I will share the skript and the link to it below. Thank you.

fontSize=15;

faceAlpha1=0.8;

faceAlpha2=1;

edgeColor=0.25*ones(1,3);

edgeWidth=1.5;

markerSize=25;

markerSize2=10;

cMap=gjet(4);

%Latticeparameters

nRepeat=3; %Number of repetitions of the lattice pattern

sampleSize=30;

nSubPenta=1;

strutThickness=2; %Set the strut thickness

[Ep,Et,VT,Ct]=diamondLattice(sampleSize,nRepeat,strutThickness,0);

[Ep,VT]=subPenta(Ep,VT,nSubPenta,3); %Sub-divide pentahedra

% strutThicknessCheck=mean(patchEdgeLengths(Fp{1},VT));

%Get element faces for visualization

Fp=element2patch(Ep,[],'penta6');

Ft=element2patch(Et,[],'tet4');

cFigure;

subplot(1,2,1); hold on;

gpatch(Fp,VT,'bw','none',1);

gpatch(Ft,VT,'bw','none',1);

axisGeom; camlight headlight;

subplot(1,2,2); hold on;

hpl=gpatch(Fp,VT,'rw','r',0.5);

hpl(end+1)=gpatch(Ft,VT,'gw','g',0.5);

legend(hpl,{'Pentahedral triangles','Pentahedra quads','Tetrahedral triangles'});

axisGeom; camlight headlight;

drawnow;

You need the additional subroutines. In this case "diamondLattice.m" and all other routines accompined by it...

After a quick bit of googling it would seem that you need to download the following toolset: gibbonCode/GIBBON: The Geometry and Image-Based Bioengineering add-On for MATLAB (github.com) and add it to the matlab path.

Afterwards, the example runs fine.

Thank you vary much, I will try that!
