A stable and efficient algorithm for the general symmetric matrix eigenproblem is given which allows the calculation of selected eigenvalues and eigenvectors in large Hylleraas-CIs. The method is based on a new version of the inverse iteration. The algorithm was successfully applied to a Hylleraas-CI for the Li-atom with ...
If the eigenvectors of A are not linearly independent, then such a diagonal decom- position does not exist and the powers of A exhibit a more complicated behavior. If T is any nonsingular matrix, then A = T BT −1 is known as a similarity transformation and A and B are said to be...

Linear transformation and corresponding matrix representation play a big role in linear algebra. By finding eigenvalues and eigenvectors of the matrix representation of that linear transformation, we can visualize what is done by the transformation between two vector spaces....
Let {e1, . . . , eh} be an orthogonal basis of Ci−1(Lk(v)) with respect to (·, ·)v which consists of v-eigenvectors. Write τv f = j a j e j . Then h ( vτv f, τv f )v ≤ Mi−1(Lk(v)) a2j (e j , e j )v ≤λim−a1x(X ) · (τv f, τ...
Example 1: Scree plots after principal component analysis Multivariate commands, such as pca and factor (see [MV] pca and [MV] factor), produce eigenval- ues and eigenvectors. The screeplot command graphs the eigenvalues, so you can decide how many components or factors to retain. We ...
