ecc2flat

Convert from eccentricity to flattening representation of the ellipsoid

Syntax

• flattening = ecc2flat(eccentricity)
  

Description

Flattening and eccentricity are two methods of defining an ellipsoid.

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 geoid vectors to be used as rows of the input, since the second element of these vectors is the eccentricity. In all other cases, all columns of the input are used.

Example

• flattening = ecc2flat(almanac('earth','geoid'))
  flattening =
      0.0034
