How to use fillup3 to color shape?

How do you use the fillup3 function to make a shape? I am able to make the flat shape using the plot3 command, but the fillup3 just produces just a black line. I read that you were supposed to use the fourth argument to specify color so I just put y for yellow.

p=[11,10,16]

q=[11,10,18]

r=[15,9,18]

M=[p;q];

fill3(M(:,1), M(:,2), M(:,3), y);

figure(2);

hold on;

G=[p;r];

fill3(G(:,1), G(:,2), G(:,3), y);

hold on;

L=[q;r];

fill3(L(:,1), L(:,2), L(:,3), y);

Undefined function or variable 'y'??

Sorry, are you asking what variable y is?

One aproach

p=[11,10,16];
q=[11,10,18];
r=[15,9,18];
M=[p;q;p;r;q;r];

i = randi(6,1,6);       % mix indices
cm = jet(6);            % create 6 colors
f1 = fill3(M(:,1), M(:,2), M(:,3), 'y');
set(f1,'FaceVertexCData',cm(i,:),...
    'edgecolor','interp',...
    'marker','*')

Hi, I was just wondering though, is it possible to use this to color the inside of the shape in?

[darova]

Sure, just collect all data together

p=[11,10,16];
q=[11,10,18];
r=[15,9,18];
M=[p;q;r];
f1 = fill3(M(:,1), M(:,2), M(:,3), 'y');

Got it, though there seems to be some kind of error, saying the expression is invalid. Am I missing any spaces or anything?
