Need help adding a function to a script

I need some help. We're programming a battleship game in class. This is the script we did together in class so far and it works perfectly:

%This is our basis for our battlehsip game

clear all
close all
clc

rowdim=input('give me the number of rows on the board: ');
coldim=input('give me the number of columns on the board: ');
GameBoard=zeros(rowdim,coldim); %defined board dimensions

battleship_row=randi(rowdim,[1 1]); %random row
battleship_col=randi(coldim,[1 1]); %random column
GameBoard(battleship_row,battleship_col)=1;

rowguess=input('guess what row the battleship is in: ');
colguess=input('guess what column the battleship is in: ');
if (rowguess == battleship_row) & (colguess == battleship_col)
    disp('You sunk the battleship! You won!');
else
    disp(' ')
    disp('Better luck next time');
    end


GameBoard(rowguess,colguess)=2
disp('KEY: battleship location:1 your guess:2');

However he wanted us to turn lines 15-22 (starting with 'rowguess' and ending with 'end' into a function and I'm not sure how to do it. I suck at functions. Can anyone help me?

This is what I have so far but once i run the script it does nothing after I guess what row or column I think the battleship could be in.

%this is our battleship game, functionized

clear all
close all
clc

rowdim=input('give me the number of rows on the board: ');
coldim=input('give me the number of columns on the board: ');
GameBoard=zeros(rowdim,coldim); %defined board dimensions

battleship_row=randi(rowdim,[1 1]); %random row
battleship_col=randi(coldim,[1 1]); %random column
GameBoard(battleship_row,battleship_col)=1;


rowguess=input('guess what row the battleship is in: ');
colguess=input('guess what column the battleship is in: ');

function [display]= results(rowguess,colguess)
if (rowguess == battleship_row) & (colguess == battleship_col)
    disp('You sunk the battleship! You won!');
else
    disp('Better luck next time');
end
end

There are a few issues here:

1. You don't call the function anywhere in your code. You need to call it where the orignial code you're replacing was.
2. You don't pass battleship_col or battleship_row into the function. Unless you pass them into the function, or define them as global (not recommended), they will be undefined in the function scope.

Dumb question but how do I call the function? I literally have no idea what im doing.

[Daniel S]

call a function generally as follows:

[out1, out2, ...] = functionName(arg1, arg2, ...)
