Create x and y vectors from - 5 to + 5 with a spacing of 0.5. Use the meshgrid function to map x and y onto two new two-dimensional matrices called X and Y. Use your new matrices to calculate vector Z, with magnitude Z = sin1 2X 2 + Y 2 2 (a) Use the mesh plotting function to create a three-dimensional plot of Z. (b) Use the surf plotting function to create a three-dimensional plot of Z. Compare the results you obtain with a single input (Z) with those obtained with inputs for all three dimensions (X, Y, Z)
