1. Consider the function f = e =Vx2+y2 a) Using the meshgrid command, generate a grid for the region -5 SX S5,-5 Sy s5 in steps of 0.5. Calculate the function in this region of space. Using the contour and colorbar commands, plot the function. Specify 50 contour levels. b) Using the gradient command, calculate the gradient of the function. Specfy a step of 0.5. Using the quiver command, plot the gradient. In both cases, label all axes and title the plots
