说明：  生成地震动反应谱的matlab函数，输入加速度时程，阻尼比，输出：1列：加速度反应谱，2列：速度反应谱，3列：位移反应谱(Matlab function for generating seismic response spectrum)

Singular spectrum analysis

说明：  MATLAB提供了多种方式从磁盘读入文件或将数据输入到工作空间，即读取数据，又叫导入数据；将工作空间的变量存储到磁盘文件中称为存写数据，又叫导出数据。(MATLAB provides a variety of ways from the disk is read into a document or data entered into the work space, that is, read data, also known as import data will work variable storage space to keep the disk file is called to write data, also known as export data .)

《gps基本原理及其matlab仿真》(西安电子科技大学)里面的程序源代码，都是自己亲自敲上的。这是第5章的。对入门很有用的。(The basic principle of GPS and the matlab simulation (xi an university of electronic science and technology) in the program source code, is knock on yourself. This is the fifth chapter. The introduction is very useful. )

The plane stress analysis refers to the problems where the thickness of the structure is very small compared to other dimensions of the structure in the XY plane. The plane stress problem is a 2D problem. The stresses in the z direction are considered to be negligible,
 
0, the stress-strain compliance relationship for an isotropic material becomes,

各种压缩感知算法的比较matlab代码，sp,cosamp, ihT,Rls，l0，l1等(different cs recovery codes.)

相关基础的MATLAB代码练习，适合初学MATLAB的同学使用，代码都是最基础的，是MATLAB视频教程的相关笔记

实现维纳滤波用于语音增强。第一步采用频域谱函数计算最佳的维纳滤波器，再对输入带噪信号进行滤波；第二步是在此基础上的改进，用了自适应的思想，及时根据当前帧的状态更新修正滤波器的系统函数，得到更精确的无噪语音信号。第三步是采用自适应LMS方法，在时域迭代计算滤波器系数，迭代次数足够多时可得到较准确的有用信号。(Implement wiener filtering used in speech enhancement. First step optimum wiener filter is obtained by using the frequency spectrum function, again to input the signal with noise filtering The second step is the improvement on the basis of this, with the idea of adaptive, and in a timely manner according to the current frame updates correction system function of the filter, get a more accurate without noise speech signal. The third step is to use the adaptive LMS method, iterative calculation in time domain filter coefficient, the number of iterations enough to get the useful signal accurately.)

说明：  仿真产生各种各态同性噪声场的噪声，需设置阵型，采样率等参数(A matab toolbox to generate an array of diffuse noise)

该程序可对模糊度固定的成功率进行计算，这对于载波相位相对定位中模糊度的求解十分重要，是检验模糊度是否正确固定的标准，从而实现精准定位。
