compass(z, attributes)

compass(x, y)

compass(x, y, attributes)

obj = compass(z)

obj = compass(z, attributes)

obj = compass(x, y)

obj = compass(x, y, attributes)


Generates a compass plot. compass(z) is equal to compass(real(z), imag(z)).



Name Description
x Specifies a real vector with values that are the x-coordinates of each arrow to plot.
y Specifies a real vector with values that are the y-coordinates of each arrow to plot.
z Specifies a complex vector with real and imaginary values that are the x- and y-coordinates of each arrow to plot.
attributes Specifies valid plot attributes. Order the plot attributes by color, point-style, and line-style. For example, 'bo-' specifies that the plot is blue, marks points with circles, and uses solid lines. attributes is a string that can take a combination of the following values:
