Diagonalize a symmetric matrix from matlab
WebJun 26, 2024 · The generalised diagonalization of two matrices A and B can be done in Matlab via. [V,D] = eig (A,B); where the columns of V are are the generalised eigenvectors of the pair ( A, B ), while D is a diagonal matrix containing the corresponding generalised eigenvalues. First, is it correct to assume that the generalised eigenvectors V are also ... WebViewed 1k times. 0. I have a large symmetric matrix in python which I want to diagonalize. The matrix I am using has a size of ~35000x35000, and I am using numpy's memmap to store the matrix (dtype=float64). However, whenever I am using the numpy.linalg.eigh routine to diagonalize the matrix. Whenever I am looking at the …

WebFILTLAN is a C++ library for computing interior eigenvalues of sparse symmetric matrices. The fact that there is a whole package devoted to just this should tell you that it's a pretty hard problem. Finding the largest or smallest few eigenvalues of a symmetric matrix can be done by shifting/inverting and using the Lanczos algorithm, but the middle of the …
