I am attempting to graph a Triangular Prism

I'm new to matLab and I am trying to graph a triangular prism. I am currently attempting to use the patch function. Is there any easier way to do this or do I just need to continue to play with current method I am using until it looks correct?

x = [0 0 0 8 8 0 8 ]
y = [0 6 3 3 0 0 6 ]
z = [0 0 4 4 0 0 0 ]
patch(x,y,z, 'r')

the way you are defining the vertices of the prism is not clear:

write the vertices coordinates vertically and introduce them horizontally, for instance the most basic prism would be, with command fill3:

X = [0 0 1 0]
Y = [0 1 0 0]
Z = [1 0 0 0]
fill3(X,Y,Z,[1 1 1 1])

the 4th input is the vector with colours for prism faces.

Now with patch:

X = [0 0 1 0]
Y = [0 1 0 0]
Z = [1 0 0 0]
patch(X,Y,Z)

There's still an open face.

To set properties of all faces use patch.

The next prism would be a cube, have a look to MATLAB help: POLYGONS > examples and how to:

You can also introduce all vertices horizontally, but you also have to define all the faces

vert = [0 0 0;1 0 0;1 1 0;0 1 0;0 0 1;1 0 1;1 1 1;0 1 1];
fac = [1 2 6 5;2 3 7 6;3 4 8 7;4 1 5 8;1 2 3 4;5 6 7 8];
patch('Vertices',vert,'Faces',fac,'FaceVertexCData',hsv(6),'FaceColor','flat')
