How can I plot a 12x12x12 matrix with a point in [1,1,1 ] , [1,1,2] , etc

I am struggling between the scatter3, the plot3 and the meshgrid so any income provided will be awesome

I would like to plot a 12x12x12 matrix with a single point/dot in ALL the coordinates. As a meshgrid but in 3D..

Any ideas?

Does "a 3 dimension 12 size matrix" mean a [3 x 12] matrix? "12x12x12 matrix" is something else. Please explain again (by editing the question, not in a comment), what your inputs are.

I can interpret your question in two different ways.

The first way, I think the command you are looking for is isosurface.

For example:

M = zeros(12,12,12);
M(3,2,5) = 1;
isosurface(M, 0.5);

The second way, I think you want meshgrid and plot3:

[X,Y,Z] = meshgrid(1:12);
plot3(X(:),Y(:),Z(:),'.');

Note: I am combining two steps here:

X = X(:);
Y = Y(:);
Z = Z(:);

This converts the matrices into column vectors instead of matrices, as plot3 does not accept 3D matrices.
