function [phi lam Xmean nbasis]=POD(Xcenergy)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% This function calculates the POD basis vectors
%
% Function inputs:
% X : (n x nsnap) snapshot matrix
% n = number of states in full space
% nsnap = number of snapshots
% cenergy : how much energy of the ensemble you want
% to capture i.e. cenergy = 99.9 (percent)
%
% Function outputs:
% phi : (n x nsnap) matrix containing POD basis vectors
% lam : (nsnap x 1) vector containing POD eigenvalues
% Xmean : (n x 1) the mean of the ensemble X
% nbasis : number of POD basis vectors you should use
% to capture cenergy (percent) of the ensemble
