Eccentricity of ellipse from flattening
Support for nonscalar input, including the special two-column syntax described below, will be removed in a future release.
ecc = flat2ecc(f)
ecc = flat2ecc(f)
ecc = flat2ecc(f)
computes
the eccentricity of an ellipse (or ellipsoid of revolution) given
its flattening f
. Except when the input has 2 columns
(or is a row vector), each element is assumed to be a flattening and
the output ecc
has the same size as f
.
ecc = flat2ecc(f)
, where f
has
two columns (or is a row vector), assumes that the second column is
a flattening, and a column vector is returned.
