自己编写的振动响应计算的matlab程序，可以运行，结果正确。(dynamic response of the system using matlab。)

试试你的运气。随机输入0到9之间的四个数，看看你能得到多少公牛，多少母牛，嘿嘿。(Try your luck. Random input between 0 to 9 the number of four to see how much bull you can get, how many cows, hehe.)

非线性方程数值解法的数学基础，有牛顿法，割线法等(Mathematical foundations of numerical solution of nonlinear equations, Newton method, secant method)

本人编写的基于最小二乘法的圆拟合程序，可直接下载使用。(I prepared the least squares method based on circle fitting procedures, can be directly download.)

有限元中LinearBarElementStiffness的matlab(FEA LinearBarElementStiffness)

计算牛顿和拉格朗日插值方法,用户输入插值结点(calculated Newton and Lagrange interpolation methods, user input interpolation nodes)

求解声学问题的边界元源程序，可以为使用边界元法求解位势问题和弹性力学问题提供启发(problem solving acoustic BEM source, for the use of the boundary element method and the potential problems of elasticity to provide inspiration)

本程序是根据jacobi过关法求实对称矩阵的全部特征值和特征向量(This procedure is based on realistic method jacobi clearance of all symmetric matrix eigenvalue and eigenvectors)

本程序用于实现快速傅里叶变换的快速算法 ％ 为代码简便所有*2操作均直接实现，实际应采用二进制左移实现 (This procedure used to realize fast Fourier transform fast algorithm of all the code is simple to operate* 2 are referred directly to realize the actual binary left should be used to achieve)

1） 应用C语言编写程序，计算弹道，并绘制结果曲线。 给出系统脱靶量统计结果（用蒙特卡洛法）。 (torpedo)
