% Ellipse analysis of time series pairs 
%   ellparams  - Ellipse parameters of a modulated multivariate oscillation.
%   ellsig     - Creates an elliptical signal from ellipse parameters.
%
% Bivariate spectral matrices
%   specdiag   - Diagonalize a 2 x 2 spectral matrix.
%   polparam   - Spectral matrix polarization parameters.
%
% Operations on elliptical time series
%   elldiff    - Ellipse differentiation.
%   ellrad     - Average and instantaneous ellipse radius.
%   ellvel     - Average and instantaneous ellipse velocities.
%   ellband    - Bandwidth of "elliptical" or bivariate analytic signals.
%   ellipseplot  - Plot ellipses.
%
% Other conversions 
%   ecconv     - Converts between eccentricity measures.
%   kl2ab      - Converts ellipse parameters Kappa and Lambda to A and B.
%   ab2kl      - Converts A and B to ellipse parameters Kappa and Lambda.
