How to draw vectors (physical 2D/3D vectors) in MATLAB?

Question

I want to know the simplest way to plot vectors in MATLAB. For example:

a = [2 3 5];
b = [1 1 0];
c = a + b;

I want to visualize this vect

Answer 1

a = [2 3 5];
b = [1 1 0];
c = a+b;

starts = zeros(3,3);
ends = [a;b;c];

quiver3(starts(:,1), starts(:,2), starts(:,3), ends(:,1), ends(:,2), ends(:,3))
axis equal
