[Octave-patch-tracker] [patch #9566] mapping package: ecc2n, n2ecc, majaxis, minaxis

Follow-up Comment #9, patch #9566 (project octave):

Thank you for looking at this.

The first flattening != first eccentricity

The value you stated is the flattening. 
If you scroll down from the wiki on flattening to Identities involving
flattening (note flat2ecc.m)

note the following: 
e^2=2*f-f^2 
so the first eccentricity is
e=sqrt(2*f-f^2)

use the WGS84 value for flattening and you should arrive at the same
eccentricity.

Hope this helps

Thanks again.
