arrowHead

Draws stealth arrows at given coordinates.

ARROWHEAD draws stealth arrows at given coordinates.

ARROWHEAD(X,Y) plots an arrow head at coordinates specified by X and Y.

ARROWHEAD(...,Name,Value) plots an arrow head with properties specified by name-value pairs.

P=ARROWHEAD(...) returns an object generated by Matlab's `patch` function.

Possible names are

- FaceColor : any input that is valid for Matlab's `patch` function,

- FaceAlpha : any input that is valid for Matlab's `patch` function,

- EdgeColor : any input that is valid for Matlab's `patch` function,

- LineStyle : any input that is valid for Matlab's `patch` function,

- ArrHeadLen: any real value, specifies length of arrow head, measured from stealth notch to tip

- ArrHeadWid: any real value, specifies width of arrow head

- Anchor : any real value or "stealth", controlling the alignment of the arrow head and coordinate [x, y],

if "stealth", then [x, y] aligns with the stealth notch,

if 1, then [x, y] aligns with the arrowhead's tip,

if 0, then [x, y] aligns with the midpoint between the two non-tip nodes,

if any other value, [x, y] aligns with the inter-/extrapolation of the above two points,

- Rotation : any real value, specifies the counterclockwise rotation in degree

- Axes : axes to which the arrow head should be added

Examples of use:

figure, hold on, grid on, daspect([1, 1, 1])

plot( 0, 0, 'rx'), arrowHead( 0, 0);

plot( 2, 0, 'rx'), arrowHead( 2, 0, Stealth=0.2);

plot( 4, 0, 'rx'), arrowHead( 4, 0, Stealth=0.2, Anchor=0);

plot( 6, 0, 'rx'), arrowHead( 6, 0, Stealth=0.2, Anchor=1);

plot( 8, 0, 'rx'), arrowHead( 8, 0, Stealth=0.2, Anchor="stealth");

plot(10, 0, 'rx'), arrowHead(10, 0, FaceColor='b', FaceAlpha=0.3, EdgeColor='g', LineStyle='-.');

plot(12, 0, 'rx'), arrowHead(12, 0, ArrHeadLen=1.5, ArrHeadWid=0.5);

plot(14, 0, 'rx'), arrowHead(14, 0, Rotation=135, Stealth=0.2);

arrowHead(16, 0, Rotation=35, Stealth=0.2, FaceColor=[0.8, 0, 0], EdgeColor="none", ArrHeadWid=0.8);
