摘要
详细分析了经典R-K算法的稳定性,计算得到了它的稳定区间.在此基础上提出了一种改进的R-K算法,它在[-∞,0]上绝对稳定,并且与经典R-K算法具有相同的计算精度.
The stability of classical R-K algorithm is analyzed in detail and the stable interval is calculated. An improved R-K algorithm to solve the quaternion differential equation is presented. The results show that it is absolute stable at the range of [ - ∞ , 0 ], and the accuracy is the same as that of classical R-K algorithm.
