I am trying to type a code in matlab which should represent the 2x2 rubiks cube but i keep on getting an error and whatever i do or search i cant seem to correct it.
this is the code:
A = [1 2; 3 4];
A(:,:,2) = [5 6; 7 8];
B = cat(3,A,[9 10; 11 12]);
B(:,:,4) = [13 14; 15 16];
B(:,:,5) = [17 18; 19 20];
B(:,:,6) = [21 22; 23 24];
PocketCube = B;
figure;
facesColor = {[1 0.5 0], [1 1 1], [1 0 0], [1 1 0], [0 0 1], [0 1 0]};
subdivisions = 2;
for i = 1:6
faceColor = facesColor{i};
[X, Y] = meshgrid(linspace(0, 1, subdivisions + 1));
Z = PocketCube(:, :, i);
vertices = [X(:), Y(:), Z(:)];
faces = reshape(1:numel(vertices)/3, [], size(X, 2));
patch('Vertices', vertices, 'Faces', faces, ...
'FaceColor', faceColor, 'EdgeColor', 'k', 'LineWidth', 1);
hold on;
grid on;
end

please point out the correction needed and any other issues if found to give the intended rubiks cube representation.

Your code will run to completion if you change the linspace command to have one fewer points.
(I did not check to see if this is a sensible result.)
A = [1 2; 3 4];
A(:,:,2) = [5 6; 7 8];
B = cat(3,A,[9 10; 11 12]);
B(:,:,4) = [13 14; 15 16];
B(:,:,5) = [17 18; 19 20];
B(:,:,6) = [21 22; 23 24];
PocketCube = B;
figure;
facesColor = {[1 0.5 0], [1 1 1], [1 0 0], [1 1 0], [0 0 1], [0 1 0]};
subdivisions = 2;
for i = 1:6
faceColor = facesColor{i};
[X, Y] = meshgrid(linspace(0, 1, subdivisions));
Z = PocketCube(:, :, i);
vertices = [X(:), Y(:), Z(:)];
faces = reshape(1:numel(vertices)/3, [], size(X, 2));
patch('Vertices', vertices, 'Faces', faces, ...
'FaceColor', faceColor, 'EdgeColor', 'k', 'LineWidth', 1);
hold on;
