利用已知数据画地貌图：
代码实现：
[x,y]=meshgrid(1:10);
h = [0,0.02,-0.12,0,-2.09,0,-0.58,-0.08,0,0;0.02,0,0,-2.38,0,-4.96,0,0,0,-0.1;0,0.1,1,0,-3.04,0,-0.53,0,0.1,0;0,0,0,3.52,0,0,0,0,0,0;-0.43,-1.98,0,0,0,0.77,0,2.17,0,0;0,0,-2.29,0,0.69,0,2.59,0,0.3,0;-0.09,-0.31,0,0,0,4.27,0,0,0,-0.01;0,0,0,5.13,7.4,0,1.89,0,0.04,0;0.1,0,0.58,0,0,1.75,0,-0.11,0,0;0,-0.01,0,0,0.3,0,0,0,0,0.01];
[xi,yi]=meshgrid(1:0.1:10);%构建插值网格
hi = interp2(x,y,h,xi,yi,'spline');%二维插值命令
surf(hi);
xlabel('x'),ylabel('y'),zlabel('h');
