WebThe numpy.linalg.eig function returns a tuple consisting of a vector and an array. The vector (here w) contains the eigenvalues. The array (here v) contains the corresponding eigenvectors, one eigenvector per column. The eigenvectors are normalized so their Euclidean norms are 1. The eigenvalue w [0] goes with the 0 th column of v. WebMar 11, 2024 · Eigendecomposition is a technique used in Linear Algebra to break down a matrix into its constituent parts.
