Eccentricity of Ellipse from Third Flattening
Find the eccentricity of an ellipse from the third flattening.
ecc = n2ecc(0.0017)
ecc = 0.0823
Input Arguments
n
— Third flattening of ellipse
numeric scalar
Third flattening of the ellipse, specified as a numeric scalar. The input
n
is defined as (a–b)/(a+b), where a is the semimajor axis and
b is the semiminor axis.
Data Types: single
| double
Output Arguments
ecc
— Eccentricity of ellipse
numeric scalar
Eccentricity of the ellipse, returned as a numeric scalar in the range [0, 1].
Version History
Introduced before R2006aR2013b: Only numeric scalars will be accepted as input
The n2ecc
function will not accept vectors or matrices as input in
