HALFPOLAR function performs the polar plot in radian angle range [0 pi]
using half polar coordinates

HALFPOLAR(phi,gain) makes a plot with phi in radians angle range [0 pi]
and gain in half polar coordinates. Phi and gain could be vector or matrix
with the same dimensions. When Phi is a vector(1XN) and vector(1XN) and
matrix(MXN)gain values are allowable. When Phi is a matrix(MXN) and then
the gain should only be matrix(MXN) with the same row numbers.

HALFPOLAR(phi,gain, linestyle) uses specified linestyle defined in cell
variable linestyle to plot phi and gain, like: linestyle = {'ko-','b--'}

HALFPOLAR(phi,gain, linestyle, xtickval) plots phi and gain with the
prescribed tick value xtickval. like: xtickval = [15 25 45 75 105]

IMPORTANT NOTE:
HALFPOLAR is designed especially for the radiated sould pressure level
demonstration. Accordingly the gain value is designed to be dB value.
the default xtickvalue is also designed to match the dB value range.
So you are permitted to modify the function in order to correctly
demonstrate data for your specified applications.

HALFPOLAR is coded straightforward without variables checking and fault
testing.The author don't take the responsibility for the program bug.

Example:
phi = linspace(0,pi,20);
gain = 80 * rand(3,length(phi)) + 40;
h = halfPolar(phi,gain,{'k-','g-.','r--','k-'},[30 40 65 80 95 120])

Another Example:
phi = linspace(0,pi,20);
gain = 80 * rand(3,length(phi)) + 40;
h = halfPolar(phi,gain,{'k-','g-.','r--','k-'},[30 40 65 80 95 120])

% Add legend to the half polar figure
legend(h,'1','2','3');

% set the specified line style and color
set(h(1),'linestyle','-.','color','b')

This works well when plotting a single data series, but the resulting figure is not a "real" MATLAB plot - axis scaling and adding data series do not work, for example.

1.3.0.0

The figure handle is obtained in order to set the specified line style, line marker and other properties. Also the legend function can be used to add the legend. The function is now more comprehensive!
