Flattening of ellipse from eccentricity
Support for nonscalar input, including the syntax f
= ecc2flat(ellipsoid), will be removed in a future release.
f = ecc2flat(ecc)
f = ecc2flat(ellipsoid)
f = ecc2flat(ecc) computes
the flattening of an ellipse (or ellipsoid of revolution) given its
eccentricity ecc. Except when the input has 2 columns
(or is a row vector), each element is assumed to be an eccentricity
and the output f has the same size as ecc.
f = ecc2flat(ellipsoid), where ellipsoid has
two columns (or is a row vector), assumes that the eccentricity is
in the second column, and a column vector is returned.
