polar gain plot in absolute units
h = abp(th, g, rays, width) h = abp(th, g) (equivalent to rays=30, width=1) h = abp(th, g, rays) (equivalent to width=1)
polar angles over [0,pi]
gain at th (g is in absolute units)
ray grid at 30 degree (default) or at 45 degree angles
linewidth of gain curve (width=1 by default)
handle to use for adding more gains and legends (see DBADD)
makes polar plot of g versus th,omnidirectionality in azimuthal angle phi is assumed,gain plot at left side over [-pi,0] is added symmetrically, max-g is assumed to be unity (e.g., as in the output of ARRAY),half-power grid circle at g=1/2 is added,for EPS output, use width=1.50 for thicker gain line, use width=0.75 for thinnest line
