AGJDN
压缩包包含三个文件:
全主元高斯-约当消元法程序AGJDN.m;基于全主元高斯-约当消元法的迭代求解病态矩阵方法AGJDNM.m;AGJDN.m的测试方程。
程序参考自:Fortran常用算法程序集(第二版) 徐世良编。AGJDN.m能求解部分病态矩阵,而AGJDNM.m对于我的测试矩阵效果不佳,但也一并上传,仅供参考。
错漏之处,还望指正。
(Gaussian-Jordan elimination base on all principal element.)

PCA算法程序 pca
PCA算法程序设计步骤:
1、去均值
2、计算协方差矩阵及其特征值和特征向量
3、计算协方差矩阵的特征值大于阈值的个数
4、降序排列特征值
5、去掉较小的特征值
6、去掉较大的特征值(一般没有这一步)
7、合并选择的特征值
8、选择相应的特征值和特征向量
9、计算白化矩阵
10、提取主分量
(PCA algorithm programming steps: 1 to mean 2, calculation of covariance matrix and its eigenvalues and eigenvectors 3, the calculation of covariance matrix eigenvalues greater than the threshold number of 4, in descending order of eigenvalue 5, remove the smaller eigenvalue 6, remove the larger eigenvalue (usually not this step) 7, the combined choice of eigenvalues 8, select the appropriate eigenvalues and eigenvectors 9, computing whitening matrix 10, principal component extraction)
