I want to randomly plot battleships on my board, but no outputs are present?

%Board
size = 10 %A-J on regular battleship and 1-10
board = zeros(size);
axis([0,10,0,10]);
title('Battleship')
letters = {'A';'B';'C';'D';'E';'F';'G';'H';'I';'J'};
set(gca,'xtick',[1:10],'xticklabel',letters);
grid on
disp(board);
%ship lengths
destroyer = [2,2];
submarine = [31,31,31];
cruiser = [32,32,32];
battleship = [4,4,4,4]
carrier = [5,5,5,5,5]
x1 = randi(10,1);
y1 = randi(1,10);
x2 = x1 + length(submarine) - 1;
col2 = y1;
board(x1:x2, y1) = submarine(1);

Regarding your flag ("delete question not necessary anymore"): that is not how this forum works. If you decide to edit away your question, everybody with editing privileges can restore it from this backup.

You are taking two approaches simultaneously in your code. You create a plot where I suspsect you want to visualize the ships, but then you are populating a matrix with the values. In order for the ships to appear on your axes, you must plot them somehow (plot, scatter, line, etc).
If you want to display board instead, perhaps somethink like heatmap will work?
%Board
size = 10 %A-J on regular battleship and 1-10
board = zeros(size);

destroyer = [2,2];
submarine = [31,31,31];
cruiser = [32,32,32];
battleship = [4,4,4,4];
carrier = [5,5,5,5,5];
x1 = randi(10,1);
y1 = randi(1,10);
x2 = x1 + length(submarine) - 1;
board(x1:x2, y1) = submarine(1)
figure
heatmap(board)
title('Battleship')
letters = {'A';'B';'C';'D';'E';'F';'G';'H';'I';'J'};
set(gca,'XDisplayLabels',letters);
