Unformatted text preview: f ( A ). This is called the spectral mapping theorem . To illustrate this with an example, generate a random 3 3 matrix, for example using A=randn(3) . Find the eigenvalues of ( I + A )( IA )1 by rst computing this matrix, then nding its eigenvalues, and also by using the spectral mapping theorem. (You should get very close agreement; any dierence is due to numerical roundo errors in the various compuations.) 1...
