`feather`

Plots vectors as arrows that start from equally spaced points on a horizontal line.

Syntax

feather(U, V)

Draws one arrow per element, with horizontal component U(k) and vertical component V(k), starting at x = k.

feather(Z)

For complex Z, uses real(Z) and imag(Z) as the components.

h = feather(___)

Also returns the graphics handles.

Description

A feather plot shows how a quantity with direction changes along a sequence, such as wind or the phase of a series of phasors. Every arrow has its tail on the baseline, so the arrows show direction and magnitude but not position.

Input arguments

U, V: Vectors of the same length with the horizontal and vertical components.
Z: Complex vector, one arrow per element.

Output arguments

h: Handles of the graphics objects created.

Example

Complex phasors

z = [1+1i, 2, 1.5-1i, -1+0.5i, 0.5i];
feather(z)

In the app, the figure is drawn below the code.
