求助三维绘图

xad111

行数和列数不相同,并且已知网格点的值zz(i,j)
x=1:row11;
y=1:col11;
[X,Y]=meshgrid(x,y);
mesh(X,Y,zz(X,Y))

显示不了
哪位大侠知道的话,请告知
非常感谢

把你的zz函数给出来，问题估计出在这个函数上

xad111

0,0,0,0,0,0,0,0
3,5,4,,6,6,2,4,6
0,0,2,0,4.5,0,0,0
0,0,0,0,0,0,0,0,0

1. zz=[0,0,0,0,0,0,0,0;3,5,4,5,6,2,4,6;0,0,2,0,4.5,0,0,0;0,0,0,0,0,0,0,0];
   
2. row11=8;
   
3. col11=4;
   
4. x=1:row11;
   
5. y=1:col11;
   
6. [X,Y]=meshgrid(x,y);
   
7. figure
   
8. mesh(X,Y,zz)
