Question

matlab中怎么对下面的程序进行二维插值并画出三维视图呢？

[x,y]=meshgrid(-2:1:2);
t=2;
Z=[(sin(t))^3 t^2 sin(t) cos(t) (sin(t))^2;t^2 sin(t) (cos(t))^4 cos(t) (sin(t))^2;t sin(t) cos(t) t^2 (sin(t))^2;sin(t) (cos(t))^3 t^2 (sin(t))^2 cos(t);(cos(t))^3 sin(t) t^2 (sin(t))^2 cos(t)];
surf(x,y,Z);

Answer 1

接着你的代码往下写:

[x1,y1]=meshgrid(-2:0.1:2);

z1 = interp2(x,y,Z,x1,y1);

figure; 

surf(x1,y1,z1);
