Hence this method can improve accuracy and efficiency of the calculation . c . based on these work upwards , an adaptively wavelet precise time - invariant integration method was proposed in this paper . in this method , an adaptive multilevel interpolation wavelet collocation method for partial difference equations ( pdes ) was conducted , in which the time complexity is less than oleg v ' s method , and then the adaptive precise integration method was combined with , so that in this method the adaptively discretes both in time domain and physical domain were realized 該方法將外推法引入求解結(jié)構(gòu)動力方程的精細時程積分法中,從而使該方法在求解非線性動力方程中可以自適應選取時間步長;需要指出的是,由于考慮了矩陣指數(shù)精細算法和外推法算法在時間離散方法上的一致性,在外推過程中,計算工作量基本沒有增加;因此,兩種方法的結(jié)合有效提高了算法的效率和精度。
