1.(2 points) Write MATLAB statements to generate a 1 by 2 array of subplots of the surface data : (x,u) ye over x coordinates ranging between 1-2m, 2n] and y coordinates ranging between l-2n, 2n] with 101 points along each direction. In the first subplot, plot the surface without gridlines, together with contour lines projected onto the x-y plane. In the second subplot, plot 40 contour lines in 3D space. 2. (1 point) If the command subplot(4,6,10) is issued in MATLAB, in which row and column of the current Figure will the plot produced by the next plot command be located
