.SH NAME
xrects - draw or fill a set of rectangles
.SH CALLING SEQUENCE
.nf
[]=xrects(rects,[fill])
.fi
.SH PARAMETERS
.TP 15
rects
: matrix of size (4,n)
.TP
fill
: vector of size n.
.SH DESCRIPTION
draws or fills a set of rectangle. each column of \fVrects\fR describes
a rectangle ( Upper Left point, width, height)
.LP
\fVrects= [ x,y,w,h ; x,y,w,h ;.....] '\fR
\fVfill(n)\fR gives the pattern to use for filling or drawing the rectangle n.
.LP
if \fVfill(n) <0 \fR, the rectangle \fVn\fR is drawn using the line style (or
color)\fV-fill(n)\fR
.LP
if \fVfill(n)> 0 \fR, the rectangle \fVn\fR is filled using the pattern (or
color)\fVfill(n)\fR.
.LP
if \fVfill(n)= 0\fR, the rectangle \fVn\fR is drawn using the current
line style (or color).
.SH EXAMPLE
.nf
plot2d([-100,500],[-50,50],[-1,-1],"022");
cols=[-34,-33,-32,-20:5:20,32,33,34];
step=20;
x=400*(0:14)/14
step = (x(2)-x(1))/2
rects=[x;10*ones(x);step*ones(x);30*ones(x)];
xrects(rects,cols);
