Plot arrows emanating from the origin
Syntax
Description
A compass graph displays the vectors with components (U,V)
as arrows emanating from the origin. U
, V
, and Z
are in Cartesian coordinates and plotted on a circular grid.
compass(U,V)
displays a compass graph having n arrows, where n is the number of elements in U
or V
. The location of the base of each arrow is the origin. The location of the tip of each arrow is a point relative to the base and determined by [U(i)
,V(i)]
.
compass(Z)
displays a compass graph having n arrows, where n is the number of elements in Z
. The location of the base of each arrow is the origin. The location of the tip of each arrow is relative to the base as determined by the real and imaginary components of Z
. This syntax is equivalent to compass(real(Z),imag(Z))
.
compass(...,
draws a compass graph using the line type, marker symbol, and color specified by LineSpec
)
LineSpec
.
compass(axes_handle,...)
plots into the axes with handle axes_handle
instead of the current axes (gca
).
h = compass(...)
returns handles to line objects.
Examples
Draw a compass graph of the eigenvalues of a matrix.
