Plot 2D/3D Vector with Arrow

Arrowline 3-D vector plot. vectarrow(p0,p1) plots a line vector with arrow pointing from point p0 to point p1. The function can plot both 2D and 3D vector with arrow depending on the dimension of the input Example: For 3D vector p0 = [1 2 3]; p1 = [4 5 6]; vectarrow(p0,p1) For 2D vector p0 = [1 2]; p1 = [4 5]; vectarrow(p0,p1)
