This is difficult for large matrices and iterative methods are much better. Two such methods are described briefly in this section.
In this section, we will explore a technique called the power method that finds numerical approximations to the eigenvalues and eigenvectors of a square matrix. Generally speaking, this method is how ...In this section, we will explore a technique called the power method that finds numerical approximations to the eigenvalues and eigenvectors of a square matrix. Generally speaking, this method is how eigenvectors are found in practical computing applications.
