非线性振动

该程序是一种最小二乘滤波算法的matlab实现程序，主要应用于非平稳信号的干扰抑制中(The program is a least squares filtering algorithm matlab implementation program, mainly used in non-stationary signal interference suppression in)

矩阵的练习 对于掌握数组的 概念很重要。如何快速掌握数组，灵活运用。(The practice of the matrix is ​ ​ very important to grasp the concept of the array. How to quickly grasp the array of flexible use.)

n of the parity check matrix

包络线去除完全用Excel函数写的包络线去除分析，仅实现了1850—2100nm的包络线去除，其他波段可自行扩展(Continuum Removal MATLAB Compiler 1. Prerequisites for Deployment . Verify the MATLAB Compiler Runtime (MCR) is installed and ensure you have installed version 7.13. . If the MCR is not installed, run MCRInstaller, located in: <mcr_root>* oolboxcompilerdeploywin32MCRInstaller.exe For more information on the MCR Installer, see the MATLAB Compiler documentation.)

用C++编写的一维和二维快速傅里叶变换程序(Prepared with C++ one-dimensional and two-dimensional fast Fourier transform procedure)

说明：  利用二阶循环统计量去除同频带干扰的影响，同时，当信号为相干信号时，也可以去相关，得到较好的结果，(Using second-order cyclic statistics to remove the influence of interference in the same frequency band)

计算机常用数值算法与程序(C++版) (Commonly used numerical algorithm of computer and program )

使用奇异值分解来帮助求解最小二乘问题，特别是在方程系数矩阵不满秩的情况下。(SGELSD computes the minimum-norm solution to a real linear least * squares problem: * minimize 2-norm(| b- A*x |) * using the singular value decomposition (SVD) of A. A is an M-by-N * matrix which may be rank-deficient.)

说明：  共轭梯度法求解线性方程组,主要采用FR共轭梯度法(solve liner solutions from CG)
