xBaseOdeGearsAndAdamsMoulton_IState Field

MeIState= an index used for input and output to specify the the state of the calculation. In the input, the values of ISTATE are as follows. MeIState=1 means this is the first call for the problem (initializations will be done). MeIState=2 means this is not the first call, and the calculation is to continue normally. In the output, ISTATE has the following values and meanings. MeIState=1 means nothing was done, as TOUT was equal to T with ISTATE = 1 in the input. MeIState=2 means the integration was performed successfully. MeIState .LT. 0 Error MeIState=-1 means an excessive amount of work (more than MXSTEP steps) was done on this call, before completing the requested task, but the integration was otherwise successful as far as T. (MXSTEP is an optional input and is normally 500.) MeIState=-2 means too much accuracy was requested for the precision of the machine being used. MeIState=-3 means illegal input was detected
