Hi I am writing a program that studies the stability of a dynamical system. I want to sort the eigenvalues of the matrix by magnitude in ascending order and then assign theses eigenvalues to a variable and then check to know those that are outside the unit circle. I am dealing with a 5 by 5 matrix. Do not want to go through  the permuation of thses eigenvalue which is lengthy. can someone help me out. JUS HOW TO ASSIGN EACH EIGENVALUE TO A VARIABLE. THANK YOU
