Plotting a triangle from 3 3x1 matrices

2 views (last 30 days)
Hello,
So I am trying to create a plot of a triabgle from three matrices a = [5; 8; 13]; b = [-5; 7; 21]; c = [12; -32; 0]; . I have used plot3 for every possible combination of vectors a, b, and c and well as every possible combination of their transposes and only seem to get two lines. Are there any other plotting methods I should try?
Thank you

a = [5; 8; 13]; b = [-5; 7; 21]; c = [12; -32; 0];
V=num2cell([a,b,c,a],2);
plot3(V{:},'-o', MarkerFace='r');
xlabel x; ylabel y; zlabel z; grid on
