.so ../sci.an
.SH NAME
xsegs - draw unconnected segments
.SH CALLING SEQUENCE
.nf
xsegs(xv,yv,[style])
.fi
.SH PARAMETERS
.TP 7
xv,yv
: matrices of the same size.
.TP
style
: vector or scalar. If \fVstyle\fR is a positive scalar,
it gives the dash style to use for all segments. If \fVstyle\fR is a negative
scalar,
then current dash style is used. If \fVstyle\fR is a vector,
then \fVstyle(i)\fR gives the style to use for segment \fVi\fR.
.SH DESCRIPTION
\fVxsegs\fR draws a set of unconnected segments given by \fVxv\fR
and \fVyv\fR. If \fVxv\fR and \fVyv\fR 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 \fVxv\fR and \fVyv\fR:
\fV(xv(i),yv(i))-->(xv(i+1),yv(i+1))\fR.
For instance, using matrices of size (2,n), the segments can be defined by:
.nf
xv=[xi_1 xi_2 ...;
xf_1 xf_2 ...]
yv=[yi_1 yi_2 ...;
yf_1 yf_2 ...]
.fi
and the segments are \fV(xi_k,yi_k)-->(xf_k,yf_k)\fR.
.SH EXAMPLE
.nf
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)
