WebApr 22, 2024 · Why do ATA and AAT have the same eigenvalues? Why is it that and have the same non-zero eigenvalues? A symbolic proof is not hard to find, but as usual, I prefer to find a way to visualize it in order to gain a better mathematical intuition. Let be an eigenvector of . We start with vector . transforms into some arbitrary vector . WebWe now prove that the eigenvalues of (AAT)k, k 1, are related to the eigenvalues of AAT. In particular, if is an eigenvalue of AAT then k is an eigenvalue of (AAT)k. Moreover, AAT and (AAT)k have identical eigenvectors. Theorem 3 Let A 2Rm n. Further, let q an eigenvector of AAT corresponding to the eigenvalue . Then the matrix (AAT)k has k as ...
Web首先将要分解的 m\times n 的矩阵 A 乘上它的转置,我们就可以得到一个 m\times m 的方阵 (AA^T) 。那么是方阵的话我们就可以对其进行特征值分解,得到 (AA^T)U=\lambda_i U 这里的 U 就是我们需要的那个 U. 同上一步,接下来将 A 的转置乘上它本身,得到一个 n\times n … WebRepository for Understanding Linear Algebra. Contribute to davidaustinm/ula development by creating an account on GitHub.
WebSep 17, 2024 · Then ATA and AAT have the same nonzero eigenvalues. Proof Given an m × n matrix A, we will see how to express A as a product A = UΣVT where U is an m × m orthogonal matrix whose columns are eigenvectors of AAT. V is an n × n orthogonal matrix whose columns are eigenvectors of ATA. WebIf is an eigenvalue of ATA, then 0. Proof. Let xbe an eigenvector of ATAwith eigenvalue . We compute that kAxk2= (Ax) (Ax) = (Ax)TAx= xTATAx= xT( x) = xTx= kxk2: Since kAxk2 0, it follows from the above equation that kxk2 0. Since kxk2>0 (as our convention is that eigenvectors are nonzero), we deduce that 0. Let 1;:::;
