ecc2flat - Flattening of ellipse with given eccentricity

Syntax

flattening = ecc2flat(eccentricity)

Description

flattening = ecc2flat(eccentricity) returns the equivalent flattening for the input eccentricities. If the input, eccentricity, is a two-column vector, only the second column is used. This allows the standard two-element ellipsoid vectors to be used as rows of the input, because the second element of these vectors is the eccentricity. In all other cases, all columns of the input are used.

Flattening and eccentricity are two methods of defining an ellipsoid.

Example

flattening = ecc2flat(almanac('earth','ellipsoid'))

flattening =
    0.0034
