三参数模型 系统辨识 自己编写的通过了测试，并写了论文(The three-parameter model system identification adopted their own written)

Tm波，单峰衍射，无边界条件，适合初学者(Tm wave, single-peak diffraction, no boundary conditions, suitable for beginners)

metodo de aproximacion en matlab para ecuaciones, newton mejorado

说明：  验证中心极限定理，即将若干个不相关随机变量相加(Verify the central limit theorem, not related to the forthcoming number of the sum of random variables)

这个程序是王永良的空间普估计理论与算法中的幅相误差校正中自校正算法，找了好久找不到源程序，此程序是本人亲自编写，此方法的缺点是容易陷入局部最优解，具体看程序仿真图(This program is estimated Pu Wang Yongliang space theory and algorithms of amplitude and phase error correction in self-calibration algorithm, for a long time could not find the source, this program is a personally written, the disadvantage of this method is easy to fall into local optimal solution, specifically to see the program simulation map)

根据输入的电路矩阵表示形式，形成节点导纳矩阵，形成因子表的过程可以看做是规格化运算和消去运算的重复过程，重复的次数和非基准点的节点个数相同。 每个过程中进行的操作都相同，首先，存储规格化因子及消去因子；其次，对本行进行规格化运算，并将其值存储在因子表中；然后，对其后的每行进行消去运算；如此循环n次得到因子表。(Representation of the input of the circuit matrix, forming a node admittance matrix formation process can be seen as a factor table normalization process operations and eliminate duplicate operations, the same number of nodes and the number of repetitions of non-reference point. Each operation carried out during the same, first of all, storage and elimination factor normalization factor secondly, the Bank normalized operations, and its value is stored in the factor table then, each row will be erased after their operation so the cycle n times to get factor table.)

说明：  newmark-beta法解多个自由度的结构动力响应，并输出结构响应图形(Newmark-beta method is used to solve the structural dynamic response of two degrees of freedom and output the structural response graph.)
