I know this has been done before but my code is finished and there must be a minor problem in my code because the only output when my grid shows up is 'miss' meaning my ships arent plotting. I know they were plotting before now I cant figure out why they aren't now. This will be my last question if someone can just help me out.
Thanks a lot
function battleship(n, names)
close all
clear all
figure
axis equal off
hold on

%board

for i=0:n-1
for j=0:n-1
% Draw board
fill([i i+1 i+1 i i],[j j j+1 j+1 j],'b')
