三维插值可以使用matlab的scatteredInterpolant函数来实现,下面是一个示例代码:x = linspace(-1,1,100);
y = linspace(-1,1,100);
z = linspace(-1,1,100);
[x_grid,y_grid,z_grid] = meshgrid(x,y,z);% Generate some random points
x_pts = 2*(rand(100,1)-0.5);
y_pts = 2*(rand(100,1)-0.5);
z_pts = 2*(rand(100,1)-0.5);% Generate some random values at these points
vals = rand(100,1);% Create a scatteredInterpolant
F = scatteredInterpolant(x_pts,y_pts,z_pts,vals);% Evaluate the interpolant at the grid points
vals_grid = F(x_grid,y_grid,z_grid);
