xsegs Scilab Group Scilab Function xsegs
NAME
xsegs - draw unconnected segments
CALLING SEQUENCE
xsegs(xv,yv,[style])
PARAMETERS
xv,yv : matrices of the same size.
style : vector or scalar. If style is a positive scalar, it gives the
dash style to use for all segments. If style is a negative
scalar, then current dash style is used. If style is a vector,
then style(i) gives the style to use for segment i.
DESCRIPTION
xsegs draws a set of unconnected segments given by xv and yv. If xv and
yv are matrices they are considered as vectors by concatenating their
columns. The coordinates of the two points defining a segment are given
by two consecutive values of xv and yv:
(xv(i),yv(i))-->(xv(i+1),yv(i+1)). For instance, using matrices of size
(2,n), the segments can be defined by:
xv=[xi_1 xi_2 ...;
xf_1 xf_2 ...]
yv=[yi_1 yi_2 ...;
yf_1 yf_2 ...]
and the segments are (xi_k,yi_k)-->(xf_k,yf_k).
EXAMPLE
x=2*%pi*(0:9)/8;
xv=[sin(x);9*sin(x)];
yv=[cos(x);9*cos(x)];
plot2d([-10,10],[-10,10],[-1,-1],"022")
xsegs(xv,yv,1:10)
