Very lost and confused. Please help
  1. Create an x vector from -5 to +5 with spacing of 0.2, and a y vector from -4 to +4 with spacing of 0.2.
  2. Use the meshgrid command to map x and y onto two new two-dimensional matrices called X and Y.
  3. Use your new matrices to calculate matrix Z, with values given by(For fun, you can include the command "plot(Z)" although plotting isn't part of this problem.)
  4. Find the minimum and maximum values Z attains on the intervals defined by x and y.
  5. Include a comment in your script that explains why the result from the previous question makes sense, mathematically speaking.

What have you tried? What is the equation for Z? Step one is:
x=-5:.2:5;
y=-4:.2:4;

I have made it to step 4. That is where I am stuck.

min(min(Z));
max(max(Z));

You did you show me how you calculated Z, but I assume Z is a matrix that was produced from the meshgrid of x and y and therefore the boundaries are already built into Z.

That clears it up. I appreciate the help.
