How plot a 3-order tensor in MATLAB

a = zeros(100,100,100);
distance = [1,21,41,61,81];
for d = 1:5
    for i=distance(d): distance(d)+19
        for j=distance(d): distance(d)+19
            for k=distance(d): distance(d)+19
                a(i,j,k) = 1;
            end
        end
    end
end

The tensor a with size (100,100,100) and all element dominate the diagonal.

How to visulize a it in MATLAB with zero is white color and one is black color. I plot in MS office, this is what I want Expected image

For matrix case, we can visualize as follow

X = zeros(100,100);
distance = [1,21,41,61,81];
for d = 1:5
    for i=distance(d): distance(d)+19
        for j=distance(d): distance(d)+19
            X(i,j) = 1;
        end
    end
end


imagesc(a)
im = imagesc(1-X)
colormap(gray(256))

And the image is 2D matrix visulize

How to do a similar way for tensor?

And how to visulize tensor with noise? like noise on matrix

You can get pretty close to the plot produced in MS Office using isosurface and isocaps. AFAIK MATLAB doesn't have any built-in way of producing oblique projections, but if you're okay with an orthographic projection the following may work for you.

color = [0.2,0.2,0.2];
p1 = patch(isosurface(a), 'FaceColor', color, 'EdgeColor', 'none');
p2 = patch(isocaps(a), 'FaceColor', color, 'EdgeColor', 'none');

isonormals(a, p1);

grid on;
