| Alternatively, consider a parameterized curve. To render a vector from the point on the curve for a given time to some other point, try: {{{ syms t; % Position functions. x(t) = cos(t); y(t) = -sin(t); z(t) = t^2; % Tangent functions. xprime(t) = -sin(t); yprime(t) = -cos(t); zprime(t) = 2*t; figure; quiver3(x(5),y(5),z(5), xprime(5),yprime(5),zprime(5)); }}} |
MATLAB quiver3
The quiver3 function creates a 3D graph of a vector.

Usage
To render a vector from the origin to the point (2,4,6), try:
figure; quiver3(0,0,0, 2,4,6);
