Help with battleship program hit and miss?

So the goal of my code is to get the computer to basically run against itself and play the game battleship. I have the randomize ship assignments, the board the title which I didn't include. I am getting stuck during the t=1:50 where I start trying to get the computer to guess random spaces and display either a 'hit' or a 'miss'. It says ginput is not supported with the heatmap, but I am not sure how else to code it.

I need a starting point on how to get the computer to guess places and show either "hit" or "miss"

Thanks

size = 10; %A-J on regular battleship and 1-10 
board = zeros(size);
%all ships are X by 1 or 1 by X
dest = 2;
sub = 3;
cruze = 3; 
bship = 4;
carry = 5;
ships = [dest, sub, cruze, bship, carry];
names = [1, 2, 3, 4, 5]; %give ships numbers
for i = 1:1:numel(names)
    shipsize = ships(i);
    ship = "not placed";
    while ship == "not placed"
        column = randi(10); %pick a start column to try to place
        row = randi(10); %pick a start row
        orient = randi(2); %1 = horiz, 2 = vert
        if board(row, column) == 0 %we can start to check
            lastcolumn = 0;
            lastcolumn = column + shipsize;
            lastrow = row + shipsize;
            score = 0;
            if orient == 1
                if lastcolumn > size
                    %do nothing - while will try again
                else
                    for j = 1:1:shipsize
                        if board(row, column+(j-1)) == 0
                            %OK
                            if j == shipsize && score == 0
                                board(row, column:column+(ships(i)-1)) = names(i);
                                ship = "placed";
                            end
                        else
                            score = 1;
                        end
                    end
                end
            end
            if orient == 2
                if lastrow > size
                    %do nothing - while will try again
                else
                    for j = 1:1:shipsize
                        if board(row+(j-1), column) == 0
                            %OK
                            if j == shipsize && score == 0;
                                board(row:row+ships(i)-1, column) = names(i);
                                ship = "placed";
                            end
                        else
                            score = 1;
                        end
                    end
                end
            end
        end
    end
end
heatmap(board)
for t=1:50 
    a = ginput()
    a(1)=ceil(a(1));
    a(2)=ceil(a(2));
    if board(a(1),a(2)) == 1
        %disp('Hit!');
        hit=hit+1;
        plot(a(1),a(2), 'rx', 'MarkerSize',34,'LineWidth',5);
        if hit == 0 
            W=msgbox('You Win!');
        end
    else
        %disp('Miss!');
        plot(a(1),a(2),'bo','MarkerSize', 24, 'LineWidth',5);
    end
end

Why use ginput if you want the computer to play against itself?

I'm pretty sure there are lots of battleship game questions in the past. Did you look at any of them? Or in the File Exchange?

Use imshow() instead of heatmap().
