how can i model a structure of nasa almond?

I want to model a nasa almond structure.

i found a code on matlab but it shows an error of

undefined function platform.

p = platform;
p.FileName = 'NASA-Almond.stl';
p.Units = 'm';
figure
show(p)

What is platform? Where did you find the code? What you want to do exactly?

i want to make a cad model of nasa-almond structure in matlab

It is a function from Antenna Tool box it seems..do you have that tool box?

[AKHILA GOUDA]

Thanks,

but i dont have this tool box.

is there any other way to make such a model. I mean using any mathematical expression.

You can use this package: https://in.mathworks.com/matlabcentral/fileexchange/25555-mesh2d-delaunay-based-unstructured-mesh-generation

Also have a look on pde toolbox matlab.

stlFileName = 'nasa.STL';

stlData = stlread(stlFileName);

% Extract the vertices and faces

vertices = stlData.Points;

faces = stlData.ConnectivityList;

patch('Vertices', vertices, 'Faces', faces, ...

'FaceColor', 'white', 'EdgeColor', 'black');

axis equal tight

view(30,30)stlData = stlread(stlFileName);% Extract the vertices and facesvertices = stlData.Points;faces = stlData.ConnectivityList;patch('Vertices', vertices, 'Faces', faces, ...'FaceColor', 'white', 'EdgeColor', 'black');axis equal tightview(30,30)
