Function aer = aer2aer(aer,az)
aer = aer2aer(aer,az,epsilon)
set the value az for the azimuth in the input matrix aer,
when the given azimuth value is NaN, or when the given
elevation is (equivalent to) -90 or +90 degrees.
The azimuth is not set, when both the given azimuth and
the given elevation are NaN.
The matrix aer has three columns and each row contains
azimuth, elevation and radius. Their definitions are
described in m-files aer2xyz.m and xyz2aer.m.
The optional third argument epsilon is a scalar for the
maximal error allowed to consider an elevation equal to
+90 or -90 degrees. Its default is 1e-6.
The function is used internally in:
-- aer2xyz.m
-- xyz2aer.m
-- aeo2flu.m
-- flu2aeo.m
