I need help on this program using mat lab .

what are the code ?

1. radDecay.m: Download the file radDecay_outline.m from Moodle. Plutonium-239 is the primary fissile isotope in nuclear weapons. Kaboom. It decays with a half-life, k, of 24 millennia into Uranium-235 by alpha emission at 5.245 MeV. Radioactive decay can be written as a first-order differential equation of the form dN dt where N is the number of particles of Pu-239 and t is time. This can be solved numerically via Euler's Method or using the actual continuous solution: n(t) = Noe-t/k Istart with 100 million particles of Pu-239, and I want to know how long before I have 1 million particles remaining. a) Write code that uses Euler's method to solve the differential equation with a time step, dt, of 2000 years. Store ALL your steps in an array of particle counts, Nt. Plot the numerical results data points as circles alongside the actual solution (as solid line) on the same plot. b) 1. radDecay.m: Download the file radDecay_outline.m from Moodle.
