abp

polar gain plot in absolute units

Calling Sequence

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)

Parameters

th

polar angles over [0,pi]

g

gain at th (g is in absolute units)

rays

ray grid at 30 degree (default) or at 45 degree angles

width

linewidth of gain curve (width=1 by default)

h

handle to use for adding more gains and legends (see DBADD)

Description

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

Examples

abp(th, g);             default (30-degree lines and 40-dB scale)
abp(th, g, 45);         use 45-degree grid lines
abp(th, g, 30, 1.5);    use thicker line for gain
