%
% The function SYSFUN must be defined as
% FUNCTION [FY, FLAG] = SYSFUN(Y)
% and must return a vector FY corresponding to f(y).
% If a user data structure DATA was specified in KINInit, then
% SYSFUN must be defined as
% FUNCTION [FY, FLAG, NEW_DATA] = SYSFUN(Y,DATA)
% If the local modifications to the user data structure are needed
% in other user-provided functions then, besides setting the vector FY,
% the SYSFUN 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 SYSFUN must set FLAG=0 if successful, FLAG<0 if an
% unrecoverable failure occurred, or FLAG>0 if a recoverable error
% occurred.
%
% See also KINInit
%
% NOTE: SYSFUN is specified through the KINInit function.
