基本谱减法 实现基本谱减法MATLAB程序，为实现改进算法提供必要支持(Basic spectral subtraction to achieve the basic spectral subtraction MATLAB program for the realization of improved algorithms to provide the necessary support)

卡尔曼静态滤波在GPS量测数据中的应用。静态模型以待测点的位置和速度作为状态变量，假定系统噪声和量测噪声为高斯白噪声。多数情况下将其看成是一个线性系统。( Application of Calman static filtering in GPS measurement data. The static model is used as the state variable, and the system noise and measurement noise are Gauss white noise. In most cases, it is considered as a linear system. )

说明：  运用高斯积分法计算一维二维三维函数的数值积分(Gaussian integration method using two-dimensional three-dimensional function of one-dimensional numerical integration)

PCA算法。PCA的目的是找到能够分离出最大方差的方向，所以首先求原来所有数据三个维度上的协方差，然后求这个协方差的特征值，最大特征值为第一个方向，从此以此类推。(PCA algorithm. The purpose of PCA is to find able to isolate the direction of maximum variance, so first find all the data in three dimensions on the original covariance, and then find the eigenvalues ​ ​ of the covariance, the biggest feature is the first in one direction, from and so on.)
