%
% The function DAEFUN must be defined as
% FUNCTION [R, FLAG] = DAEFUN(T, YY, YP)
% and must return a vector R corresponding to f(t,yy,yp).
% If a user data structure DATA was specified in IDAInit, then
% DAEFUN must be defined as
% FUNCTION [R, FLAG, NEW_DATA] = DAEFUN(T, YY, YP, DATA)
% If the local modifications to the user data structure are needed
% in other user-provided functions then, besides setting the vector YD,
% the DAEFUN function must also set NEW_DATA. Otherwise, it should set
% NEW_DATA=[] (do not set NEW_DATA = DATA as it would lead to
% unnecessary copying).
%
% The function DAEFUN must set FLAG=0 if successful, FLAG<0 if an
% unrecoverable failure occurred, or FLAG>0 if a recoverable error
% occurred.
