I would like to extract x, y and z data coordinates from this function.

My plot:

f_gy = @(x,y,z) sin(x).*cos(y) + sin(y).*cos(z) + sin(z).*cos(x);
x_gy_l = 0*pi;
x_gy_u = 6*pi;
y_gy_l = 0*pi;
y_gy_u = 6*pi;
z_gy_l = 0*pi;
z_gy_u = 6*pi;
% Mesh Density
MD_gy = 50;
% Face Color
C_gy = 'red';
p = fimplicit3(f_gy, [x_gy_l x_gy_u y_gy_l y_gy_u z_gy_l z_gy_u], 'meshdensity', MD_gy, 'facecolor', C_gy);

How can I get the data in the workspace as an array?

Thanks

Were you ever able to figure this out? Looking to do the same thing.

Unfortunately, currently MATLAB does not support this workflow for implicit surface plot.
