An N by N by N matrix code

How do I code for NxNxN matrix using a letter.

Answer 1

[KSSV]

text(0.5,0.5,'D','FontSize',90,'Color','k')axis offI=frame2im(getframe(gcf));iwant = imresize(I,[50 50]) ;imshow(iwant)

[dunphy]

I=frame2im(getframe(gcf));

what does this one does?

[KSSV]

That will convert the plot into image

[dunphy]

text(0.5,0.5,'D','FontSize',90,'Color','k')

what are these for?

[Spaceman]

text adds text to one point, specifying x and y as scalars. i.e. (0.5,0.5)

'D' is what appears in the image.

'Fontsize',90 specifies how large the D will be.

'Color','k' dictates the D will be black.

Answer 2

[Walter Roberson]

N = 20;   %for example
Letter = 'D';  %for example
Array3d = repmat(Letter, N, N, N);

Answer 3

[DGM]

For sake of ridiculousness:

N = double('d'); % using a letter
myarray = zeros(N,N,N); % a NxNxN array
size(myarray)

ans = 1×3

100 100 100

Yes, I did think about creating a volumetric image of a letter, but I'm lazy today.
