Compute some eigenvalues of a matrixDavid M. Kaplan
eigenvalues have absolutely NO meaning for a matrix that is not square. Perhaps you are confusing the singular value decomposition with eigenvalues. Perhaps you want to do a PCA. We can't read your mind to know what is the source of your confusion. ...
where n runs from 0 to infinity, meaning the full matrix is infinite-dimensional. My Questions: 1- How can I define this density matrix in Mathematica? 2- Is there a more efficient way to represent it symbolically? 3-What is the best approach to compute its eigenvalues numerically?
Yeah, I know there are many functions for Fortran 95 to compute the eigenvalue of real matrix. But in my test, the syevd is the most fast function than other functions, such as the sygvx, which can select eigenvalues. So I want to konw which function is the...
the inverse of the matrix is= [[-0.2173913 -0.30434783 -0.26086957] [-0.04347826 -0.26086957 0.34782609] [ 0.39130435 0.34782609 -0.13043478]] The code and the output for example 1 Also read:Numpy linalg.eig – Compute the eigenvalues and right eigenvectors of a square array ...
