may be zero for pure relative error test tem the relative tolerance must be greater than or equal to
subroutine xermsg(LIBRAR, SUBROU, MESSG, NERR, LEVEL)
OCTAVE_EXPORT octave_value_list return the value of the option it must match the dimension of the state and the relative tolerance must also be a vector of the same length tem it must match the dimension of the state and the absolute tolerance must also be a vector of the same length The local error test applied at each integration step is xample roup abs(local error in x(i))<
