5.4 (a) Write a program that creates the grid and then makes a mesh plot and a surf plot of the function Z X*Y X*Y+X2 Over the domain 5X10 and 0 Y 10 by using the increment of 0.5. (b) Create a Gaussian distributions for X, Y, Z using peaks(50) function. Use surf function to plot a color map by default and set the shading as interpolated.
