InvMat
- 利用矩阵的奇异值分解压缩图像，先将图像分块，对各块中的每个对应象素内积得到相关矩阵A，然后对A进行奇异值分解，选择n（n<N）个较大的特征值对应的特征向量，利用该向量与各块图像内积来压缩和恢复图像-matrix of singular value decomposition image compression, image first block of the block of each pixel corresponding to be associated with the plot
幂法求主特征对

反幂法
- 使用反冥法算特征值和特征向量的算法。-use of anti-counting method offerings eigenvalues and eigenvectors of the algorithm.
lu_fac_all
- lu function file has been made in MATLAB/GUI for obtaining eigenvalues of a random square matrix. This function uses triangular top and bottom triangle step by step.
Eigenvalues
- 利用正交幂法构建一组正交向量，求矩阵所有的特征向量- Matrix method using orthogonal power all eigenvectors
