[Octave-patch-tracker] [patch #10022] [octave forge] (mapping) Auxillary Latitudes

[Philip Nienhuis]

Follow-up Comment #9, patch #10022 (project octave):

I compared con2geo with Matlab r2021b:

>> spheroid = referenceEllipsoid ('wgs84');
>> converter = map.geodesy.ConformalLatitudeConverter (spheroid)
converter = 
  ConformalLatitudeConverter with properties:

    Eccentricity: 0.0818
>> chi = [0:15:90]
chi =
     0    15    30    45    60    75    90
>> inverse (converter, chi)
ans =
         0   15.0965   30.1669   45.1923   60.1662   75.0958   90.0000
>> forward (converter, chi)
ans =
         0   14.9041   29.8337   44.8077   59.8332   74.9036   90.0000

In Octave, with con2geo:

>> con2geo (chi)
ans =
         0   15.1117   30.1821   45.1923   60.1510   75.0806   90.0000
>> geo2con (chi)
ans =
         0   14.9041   29.8337   44.8077   59.8332   74.9036   90.0000


so it seems geo2con.m works properly but con2geo.m's output doesn't match
Matlab.
