In numerical analysis, inverse iteration (also known as the inverse power method) is an iterative eigenvalue algorithm. Theory and convergence · Calculate inverse matrix or...

The inverse power method, which finds the smallest eigenvalue of a matrix essentially by using the Power Method on the inverse of the matrix.

The power method applied to (A − sI)−1 is called the inverse power method with shift; it is at the heart of many state-of-the-art methods. This “shifted inverse ...

о The idea can be used to work on the matrix A -bI instead of A with the hope that the ratio of the first two dominant eigenvalues i -b will become smaller.

The inverse power method is then invoked to refine the numerical values and gain full precision. To discuss the situation, we will need the following ...

9 мая 2022 г. · The document discusses using the inverse power method to find the smallest eigenvalue of a matrix.

The Inverse Power Method homes in on an eigenvector associated with the smallest eigenvalue (in magnitude). Notice that this means that \(A \) is nonsingular.
