Anu - you may need to provide some context. Do you just have one vector? What are its dimensions? Have you looked at plot3?

Hi Geoff, thanks for the response. I have plotted a tangent plane to a surface. Using plot3 command highlighted the point on the surface. Now I want to be able to plot the normal vector at the point. Thanks.

A 3D vector has got 3 coordinates for Point 1, and 3 coordinates for Point 2. Point1(x1,y1,z1) Point2(x2,y2,z2)
Take X = [x1 x2]; Y = [y1 y2]; Z = [z1 z2]
Doing Plot3(X,Y,Z) will plot a 3D vector.
