Hello can you please help me with the code for this box of Os' and Xs'? So far I've done this but I only print one line.

n=input('Enter length')
for i= 1:n
    for j=1:n
        if i==1||i==n
            fprintf('x')
        elseif 1==2 | 1==n-1
            if j==1 |j==n
                fprintf('x')
            else
                fprintf('o')
            end
        end
        if(i==3)| (i==(n-2))
            if j==2 |j==n-1
                fprintf('o')
            else 
                fprintf('x')
            end
      
            if i==1 | j==3 | j==n-2 | j==n
            fprintf('x')
        elseif j==2 | j==n-1
            fprintf('o')
        end
        end
    
    end
end
fprintf('\n')

HINT: your only newline print statement is at the complete end of all code...

As dpb mentioned, you need to indicate when to move to the next line (which is only done at the very end of your code).

Here's an alternative I put together just for fun.

n = 10;  
m = nan(n,n);                 
% loop through each of the 3 outer layers
for i = 1:3
    m(i:n-i+1,i) = i;             %left edge
    m(i,i:n-i+1) = i;             %top
    m(end-i+1,i:n-i+1) = i;       %bottom
    m(i:n-i+1,end-i+1) = i;       %right
end
% odd numbers become "x"s, even numbers become "o's and NaNs become empties
mcell = cell(size(m)); 
mcell(mod(m,2)==1) = {'x'}; 
mcell(mod(m,2)==0) = {'o'}; 
mcell(isnan(m)) = {' '}; 
% Print to command window as nxn char array
 reshape(char(mcell),n,n)

Result:

 ans =
  10×10 char array
    'xxxxxxxxxx'
    'xoooooooox'
    'xoxxxxxxox'
    'xox    xox'
    'xox    xox'
    'xox    xox'
    'xox    xox'
    'xoxxxxxxox'
    'xoooooooox'
    'xxxxxxxxxx'
