[Octave-patch-tracker] [patch #8377] [octave forge] (mapping) 3D Coordinate system conversion functions for Geodesy

[anonymous]

Follow-up Comment #27, patch #8377 (project octave):

Hello, 

Thank you for your patience
I have tracked down where these issues were coming from. 
I also added some tests for enu2uvw

Attached is the diff -u against your files


I also came across a very strange thing with assert

>> test aer2geodetic
***** test
 [lat2, lon2, alt2] = aer2geodetic (33, 70, 1e3, 42, -82, 200);
 assert ([lat2, lon2, alt2], [42.002582, -81.997752, 1.1397e3], 10e-6)
 [lat2, lon2, alt2] = aer2geodetic ( 0.575958653158129, 1.22173047639603, 1e3,
0.733038285837618, -1.43116998663535, 200, "", "rad");
 assert ([lat2, lon2, alt2], [42.002582, -81.997752, 1.1397e3], 10e-6)
!!!!! test failed
ASSERT errors for:  assert ([lat2, lon2, alt2],[42.002582, -81.997752,
1.1397e3],10e-6)

  Location  |  Observed  |  Expected  |  Reason
    (3)       1139.7018      1139.7      Abs err 0.0017996 exceeds tol 1e-05
>> test aer2geodetic
***** test
 [lat2, lon2, alt2] = aer2geodetic (33, 70, 1e3, 42, -82, 200);
 assert ([lat2, lon2, alt2], [42.002582, -81.997752, 1.1397018e3], 10e-6)
 [lat2, lon2, alt2] = aer2geodetic ( 0.575958653158129, 1.22173047639603, 1e3,
0.733038285837618, -1.43116998663535, 200, "", "rad");
 assert ([lat2, lon2, alt2], [42.002582, -81.997752, 1.1397018e3], 10e-6)
!!!!! test failed
ASSERT errors for:  assert ([lat2, lon2, alt2],[42.002582, -81.997752,
1.1397018e3],10e-6)

  Location  |  Observed  |  Expected  |  Reason
    (1)        0.73308      42.0026      Abs err 41.269 exceeds tol 1e-05
    (2)        -1.4311      -81.9978     Abs err 80.567 exceeds tol 1e-05


So the only difference was improving the decimal for the assert expected value
from 1.1397e3 to 1.1397018e3 and then my observed changed drastically.
