How to plot one single vector in MATLAB

Best Answer

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.

MATLAB: Line of arbitrary length through 2 points in 3-D

You cannot create a line with arbitrary length. You have to decide for a specific start- and end-point.

nx = x2 - x1;
ny = y2 - y1;
nz = z2 - z1;
len = 1000;
xx = [x1 - len*nx, x2 + len*nx];
yy = [y1 - len*ny, y2 + len*ny];
zz = [z1 - len*nz, z2 + len*nz];
H = plot3(xx, yy, zz);
set(H, 'XLimInclude', 'off', 'YLimInclude', 'off', 'ZLimInclude', 'off');

The XLimInclude feature is not documented, see Undocumented: liminclude
