% Converts from polar sensor coordinates to

% Polar coordinates are defined as radius, azimuth, and elevation.

% Inverts SensorToPolar.

% See also SensorToPolar, SensorToCyl, CylToSensor.

% 9/26/93 dhb Added calData argument.
% 2/6/94 jms Changed 'polar' to 'pol'
% 2/20/94 jms Added single argument case to avoid cData.
% 4/5/02 dhb, ly New calling interface.
% 11/6/06 dhb Only allow one input arguemnt.
