RESEARCH ON THE RECURRENCE FORMULAS OF THE WHOLE THREE ORDER NUMERICAL METHODS AND THE EXPERIMENT ORDER FOR INITIAL VALUE PROBLEM OF ORDINARY DIFFERENTIAL EQUATIONS
According to some composition formulas for the initial value problem of ordinary differential equations cannot got the results of the highest order of the correction equation,this paper presented a kind of new methods of the three order recurrence and gave the process for their derivation.Then,their correlation,stability and convergence were proved.And finally,on the bases of the test data,the experiment order was presented.Through the contrast of the test data,the new methods presented in the paper were pr...
