WebDec 29, 2008 · There is a very fundamental theorem that says if L is a linear transformation from R n to R m, then the rank of L (dimension of L (R n) plus the nullity of L (dimension of kernel of L) equals m. In order to talk about the eigenvalues of a matrix, it must be from R n to R n, square as you say: the rank plus nullity = n. WebMar 29, 2024 · Solution. The matrix A + I n is nonsingular, otherwise − 1 is an eigenvalue of A but by assumption it is impossible. Since the matrix A + I n is nonsingular, it has full rank. Since A + I n is n by n matrix, its rank must be n. java static import enum
