求不规则波导的散射参数的matlab程序，使用的matlab的微分工具箱（有限元法），总的来说还不错，附带实验报告。(Scattering parameters of irregular waveguides matlab program, using a differential matlab toolbox (finite element method), on the whole pretty good, with a test report.)

matlab的追赶法，追赶法是适用于三对角矩阵的线性方程组求解的方法，并不适用于其他类型矩阵，及matlab的gauss求解方程方法，牛顿插值法，拉格朗日插值法。(matlab chasing method chasing method is applicable to the tridiagonal matrix method for solving linear equations, does not apply to other types of matrix and matlab gauss solving equations method, Newton interpolation, Lagrange interpolation.)

说明：  非线性滤波器信息泄漏的关键问题研究及其说明(Nonlinear filter information disclosure and description of the key issues)

把加速度信号变为速度信号和位移信号。用的是反频谱法(Acceleration signal into a displacement signal)

matlab数学形态学处理里面，一维信号的膨胀腐蚀等没有现成的公式，编程为解决一维信号的处理问题。(-inside matlab mathematical morphology, the expansion of one-dimensional signal no ready formula for corrosion, programming to address the problem of one-dimensional signal processing.)

在matlab里面，构造三次样条插值函数s(x)来模拟一只飞鸟外形的上部，根据已知的测试数据。(In matlab inside, construct cubic spline interpolation function s (x) to simulate the shape of the upper part of a bird, according to the known test data.)

重要参数的提取，调试通过可以使用，可以实现模式识别领域的数据的分类及回归，是国外的成品模型，多目标跟踪的粒子滤波器，包含位置式PID算法、积分分离式PID。( Extract important parameters, Debugging can be used, You can achieve data classification and regression pattern recognition, Foreign model is finished, Multi-target tracking particle filter, It contains positional PID algorithm, integral separate PID.)

用MATLAB实现的一些有限元程序，共有113个(Use MATLAB to achieve some of the finite element program, a total of 113)
