That will convert the plot into image

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.

@KSSV I do not understand how this solution is intended to produce an N x N x N matrix. At most it produces a 50 x 50 x 3 matrix, but 50 x 50 x 3 is very different than 50 x 50 x 50.

N = 20; %for example
Letter = 'D'; %for example
Array3d = repmat(Letter, N, N, N);
For sake of ridiculousness:
N = double('d'); % using a letter
myarray = zeros(N,N,N); % a NxNxN array
size(myarray)
Yes, I did think about creating a volumetric image of a letter, but I'm lazy today.

This is the final line from @KSSV answer, and does not make any sense without the previous code posted by KSSV.
