对已知的多项式p(x)利用用线性表的数据结构进行加法,乘法,微商运算
加法的时间复杂度为O(n+m)
乘法的时间复杂度为O(nm)
微分的时间复杂度为O(n)
排序的平均时间复杂度为O(nlogn)
程序优点:通过顺序表和链表结合使用,使乘法合并同类项的时间复杂度降为O(1),乘法本身的时间复杂度也达到下界。
程序提供了有好的界面,并且有较好的容错性,输入输出人性化,符合人的习惯。
用快速排序代替了插入排序,使本程序能应对较大的数据。
程序缺点:系数和指数有范围限

GprMax的理论基础是时域有限差分(FDTD)方法。时域有限差分方法直接将Maxwell方程作差分离散,利用二阶精度的中心差分近似把Maxwell方程中的微分算符直接转换为差分形式,在空间和时间上对电场和磁场交替间隔取样,使计算过程完全模拟电磁波逐步传播以及与目标物体相互作用的过程。-GprMax is based on the theory of the finite difference time domain (FDTD) method. The finite difference ti

对一个具有多目标的图像进行分割,对函数进行MATLAB定义,并设定相应的时间、空间步长,在演化过程中,对水平集的计算采用二阶基本无震荡差分格式,新初始化函数采用一阶基本无震荡差分格式,迭代时水平集每更新10次重新初始化水平集一次。这样,我们基本可以将简单的多目标图像进行分割。
