Matlab画图 X Y上不同个点的数据和对应Z的数据 怎么画三维曲面图？

Question

例如：有数据X=[2,4,6,7,8];
Y=[0.4,0.6,0.8,0.9,1.0,1.2,1.4,2.0,3.10,4.3,5.5,6.0,7.0];
Z=[
0.446, 0.419,0.229,0.688, 0.012,
0.457, 0.473, 0.400, 0.396, 0.372,
0.463,0 .471, 0.497,0.417, 0.431,
0 .504, 0.492, 0.475,0.140, 0.519,
0 .837, 0.894, 0.774,0 .778, 0.392,
0 .997, 0.637,0 .928, 0.881, 0.061,
0.751,0 .719,0 .711,0 .692, 0.669,
0 .658, 0.639, 0.675, 0.655, 0.617,

>> [X,Y]=meshgrid(X,Y);
>> surf(X,Y,Z)
数据太少，绘制出来的图形效果不太好。本回答被提问者采纳
