WebJan 2, 2024 · Eigendecomposition provides us with a tool to decompose a matrix by discovering the eigenvalues and the eigenvectors. This operation can prove useful since it allows certain matrix operations to be easier to perform and it also tells us important facts about the matrix itself. For example, a matrix is only singular if any eigenvalues are zero. http://ee.stanford.edu/~gray/toeplitz.pdf
