plot 2 3D vectors in Matlab

Dear all,

I have these vectors

a = [1 2 -3];
b = [-3 12 -13];

Both start from c=[0 0 0];

How can I plot them in a 3D envirorment?

Can you provide with a sample code?

% vectors
a = [1 2 -3];
b = [-3 12 -13];

% starting point
C0 = [0 0 0];

% put vector in a matrix, to make the code more flexible (e.g. more vectors)
V = [a; b];

% replicate the starting point for all vectors
C = repmat(C0,size(V,1),1);

% plot
figure, hold on
quiver3(C(:,1),C(:,2),C(:,3),V(:,1),V(:,2),V(:,3))

% change point of view
view([1 1 1])
