WebSep 17, 2024 · The transpose of a row vector is a column vector, so this equation is actually the kind we are used to, and we can say that \(\vec{x}^{T}\) is an eigenvector of \(A^{T}\). In short, what we find is that the eigenvectors of \(A^{T}\) are the “row” eigenvectors of \(A\), and vice–versa. [2] Who in the world thinks up this stuff? It seems ...
