Create m-file scripts/functions to solve problem in MATLAB

A substance is said to be subject to exponential decay if it decreases at a rate proportional to its value. Symbolically, this can be expressed as the following differential equation, where N is the quantity and L (lambda) is a positive number called the decay constant: dN/dt = -LN The solution to this equation is: N(t) = N(0)e^Lt Here N(t) is the quantity at integer time t, and N(0) is the (initial) quantity (at time t=0) and L is the decay constant. Larger decay constants make the quantity vanish much more rapidly. Use this fact to create a test table and then write the function called exp Decay (with three arguments N(0), L, t and one return value N(t)) to solve the problem. Use your test table to test your function. Show how to call your function and save the returned value in a variable named future Quantity. Design will be done in lecture or lab
