z应该怎么改?

>> [x,y]=meshgrid(-5:0.1:5);
>> z=5;
>> surf(x,y,z);shading interp;
Error using surf (line 75)
Z must be a matrix,not a scalar or vector

matlab使用插值进行着色处理Z must be a matrix,not a scalar or vector

z应该这样写：z=5*ones(size(x));
surf和mesh中x,y,z必须是同样维度的矩阵.

完整代码如下：

clear
clc
[x,y]=meshgrid(-5:0.1:5);
z=5*ones(size(x));
surf(x,y,z);
shading interp;

运行出来的结果如下：
