Third flattening of ellipse from eccentricity
Third Flattening of Ellipse from Eccentricity
Find the third flattening of an ellipse from the eccentricity.
n = ecc2n(0.0818)
n = 0.0017
ecc — Eccentricity of ellipse
Eccentricity of the ellipse, specified as a numeric scalar. The value of
ecc must be in the range [0, 1].
n — Third flattening of ellipse
Third flattening of the ellipse, returned as a numeric scalar. The output
n is defined as (a–b)/(a+b), where a is the semimajor axis and
b is the semiminor axis.
Version HistoryIntroduced before R2006a
R2013b: Only numeric scalars will be accepted as input
ecc2n function will not accept vectors or matrices as input in
a future release. To update your code, specify a numeric scalar instead.
