http://persson.berkeley.edu/mltrid/index.html Webeig is a Python function that utilises the numpy linalg package to compute the eigenvalues and eigenvectors of a matrix. It returns the eigenvalues and eigenvectors as one eigenvector per column of a matrix, as seen in the code below. The vector w contains the eigenvalues of the matrix A, and the matrix V has one eigenvector for each column. microsoft word business card layout

A tridiagonal matrix is a matrix that is both upper and lower Hessenberg matrix. In particular, a tridiagonal matrix is a direct sum of p 1-by-1 and q 2-by-2 matrices such that p + q/2 = n — the dimension of the tridiagonal.
