在 MATLAB Online 中打开

Error using matlab.graphics.chart.primitive.Surface

Error setting property 'CData' of class 'Surface':

Value must be a 2D or 3D array of numeric type.

clc
    x = linspace(0, 3, Nx*3);
    y = linspace(0, 1, Ny*1);
    z = linspace(0, 1, Nz*1);
    [X, Y, Z] = meshgrid(x, y, z);
    EQ_gy = cos(2*pi*X).*sin(2*pi*Y) + cos(2*pi*Y).*sin(2*pi*Z) + cos(2*pi*Z).*sin(2*pi*X);
    [y,z] = meshgrid(linspace(0,1,20));
    for off=0.5:0.5:2.5    
     x = off + zeros(size(z));
         surf(x,y,z,EQ_gy)
         hold on
     end
       hold off
       xlim([0 2.5])

you cannot use surf to display solid volumes. See volshow

If you have three independent input variables and one dependent output variable, then you should consider: slice or isosurface or volshow or volumeviewer
