ssume that a matrix A is diagonalizable and we have calculated the diagonalization of A, i.e. A = VAV-¹. Also, assume all of the igenvalues of A are real and positive where |A1| > |A2| > |A3| > · · · > |An |- a) Calculate the diagonalization of A - σI. int: your answer should involve V, V-¹, A and oI
