use matlab

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=sin(X2+Y2)I a. Use the mesh plotting function to create 3 -dimensional plot of Z b. Use the surf plotting function to create 3 -dimensional plot of Z
