Stack Exchange … WebIn the following pages when we talk about finding the eigenvalues and eigen-vectors of some n×nmatrix A, what we mean is that Ais the matrix representa-tion, with respect to the standard basis in Rn, of a linear transformation L, and the eigenvalues and eigenvectors of Aare just the eigenvalues and eigenvectors of L. Example 1.
Weba. Show that if A and B have independent columns, so does AB. b. Show that if A and B have independent rows, so does AB. Exercise 5.4.19 A matrix obtained from A by deleting rowsand columns is called a submatrix of A. If Ahas an invertible k×k submatrix, show that rank A ≥k.
