sample, rowvar is set to 0. CovMat is the covariance matrix. (3) Calculate the feature value and Feature Matrix call the eig function in linalg of the linear algebra module in numpy. The feature value and feature vector can be obtained directly from covMat: eigVals,eigVects=np.linalg.eig(np.mat(covMat)) EigVals stores feature values and row vectors. EigVects stores feature vectors. Each column carries a feature vector. Feature values correspond to f

In the job need to find the eigenvalues and eigenvectors of a matrix, of course, the students will use the MATLAB built-in functions [V, D] = Eig (A), so that the diagonal matrix D is a small-to-large arrangement of the characteristics of the value. Some students want to be able to separate this diagonal element into a row vector or column vector, but also hope that the characteristics of the value from large to small arrangement, in order to achieve
