MATLAB MATLAB MATLAB Model description The logistic map is a function that is often used to model population growth. It is defined by P(t+1) = rP(t) (1 -P(t)/K) Here, P(t) represents the density of a population at year 1, the parameter r is a growth rate and the parameter K is the maximum possible population density (known as the carrying capacity). This equation says that if we know the density at one year, we can substitute it into the right-hand...

Exercise 25.5. On the region in RP where x + 2y > 0, consider the function f(x, y) = 3x²y – 2xy + 2V x + 2y. (a) Compute the Hessian matrix symbolically (i.e., as a 2 x 2 matrix whose entries are functions of x, y). (b) Compute the Hessian matrix at (x, y) = (-1,1) and at (1,0) (as matrices whose entries are fractions). (c) Using (b), determine the quadratic approximations to f(-1 + h, 1+ k) and...

Exercise 3. Consider the continuous-time signal (t) = sin(at) where a is a positive finite value. Let y(t) = zº(t). The following signals are sampled using a train of impulses with periodicity T, 8(t – kt): signal z(t) is sampled to obtain 2.(t), and signal y(t) is sampled to obtain yo(t). A) Determine the range of values for T that allows complete recovery of r(t) from .(t) [pt. 10]. B) Determine...

4. Consider an experiment in which you count the number of decays from a radioactive sample in a short time interval At starting at t-0. The distribution for this kind of experiment is the exponential function: f(t) where ? is a positive constant. (a) Sketch this function (The distribution is zero for t<0 because the experiment begins at t-0. (b) Show that the function is properly normalized. (c) Find the mean time <t> of the...

Consider a population P(t) that is varying with time. A mathematician will say that the rate at which the population is changing with respect to time is given by the derivative dP dt On the other hand, a population biologist will say that the rate of change is roughly proportional to the population. This means that there is a constant r, called the reproductive rate, such that...
