6.10. Application of Eigenvalues and Eigenvectors¶. Eigenvalue / Eigenvector problems are one of the more important linear algebra topics. Eigenvalues and eigenvectors are used to solve systems of differential equations, but more generally they are used for data analysis, where the matrix represents data rather than coefficients of a system of equations.

Compute the eigenvalues and right eigenvectors of a square array. LAX-backend implementation of eig() . This differs from numpy.linalg.eig in that the return 

[V,D,W] = eig(A,B) also returns full matrix W whose columns are the corresponding left eigenvectors, so that W'*A = D*W'*B. The generalized eigenvalue problem is to determine the solution to the equation Av = λBv, where A and B are n-by-n matrices, v is a column vector of length n, and λ is a scalar. The values of λ that satisfy the equation are the generalized eigenvalues. jax.lax.linalg.eig¶ jax.lax.linalg. eig (x, compute_left_eigenvectors = True, compute_right_eigenvectors = True) [source] ¶ Eigendecomposition of a general matrix.
