I developed 3D matric as per my intention as below and now I want to export it to a STL file and view it. As I am new to the Matlab I downloaded the code from https://uk.mathworks.com/matlabcentral/fileexchange/27733-converting-a-3d-logical-array-into-an-stl-surface-mesh?focused=5235499&tab=function (Used the convert voxels to stl example file) and tried to develop my function. But I could not successful as there was a error with a mat.file. I tried to rectify the mat.file issue.Still unsuccessful.
My SUCCESSFUL voxel code
% Building the 10X10X10 Voxel Cube
B=zeros(10,10,10);
B([1,10],:,:)=1;
B(:,[1,10],:)=1;
B(:,:,[1,10])=1;
nnz(B==1)
nnz(B==0)
My UNSUCCESSFUL voxel conversion to stl code
%Load an example dataset. The contents are as follows:
% gridDATA 30x30x30 216000 double array
% gridX 1x30 240 double array
% gridY 1x30 240 double array
% gridZ 1x30 240 double array
load ('cube.mat','B')
%Convert the binary data to an STL mesh:
[faces,vertices] = CONVERT_voxels_to_stl('temp.stl',gridINPUT,gridX,gridY,gridZ,'ascii');
%Plot the original data:
figure;
imagesc(squeeze(sum(gridINPUT,3)));
colormap(gray);
axis equal tight
%Load and plot the stl file:
figure
[stlcoords] = READ_stl('temp.stl');
xco = squeeze( stlcoords(:,1,:) )';
yco = squeeze( stlcoords(:,2,:) )';
zco = squeeze( stlcoords(:,3,:) )';
[hpat] = patch(xco,yco,zco,'b');
axis equal
Note== Always error in load command!!. I downloaded this code from the above link and trying to match for my work.
Appreciate your comments

What about isosurface?
clc,clear
clf
r = 10;
[x,y,z] = meshgrid(-r:r);
v = x.^2+y.^2+z.^2<r^2;
h = isosurface(x,y,z,v,0.9);
patch(h,'facecolor','r')
axis vis3d
