compass
Description A compass plot displays direction or velocity vectors as arrows emanating from
the origin. X, Y, and Z are in Cartesian coordinates and plotted on a circular
grid.
compass(X,Y) displays a compass plot having n arrows, where n is the number
of elements in X or Y. 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 [X(i),Y(i)].
compass(Z) displays a compass plot 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(...,LineSpec) draws a compass plot using the line type, marker
symbol, and color specified by LineSpec.
h = compass(...) returns handles to line objects.
Examples Draw a compass plot of the eigenvalues of a matrix.
Z = eig(randn(20,20));
