Overview
Consider The two-parametric Mittag-Leffler function as given in the "first photo". The question is: "summarise the main monotonicity results of "2ndphoto" function and confirm them numerically for alpha in (1,2)". So, for more details, the question is: is E_alph,beta(-x) monotonic for 1<alpha<2, beta>alpha? There is a Matlab function for the Mittag-Leffler function that you can use to graph the function for the cases 1<alpha<2, beta>alpha to confirm the main monotonicity results numerically.
