I wish to make a Interactive tic tac toe game for a project.

I wish to make it so that player 2 can be a direct input from a person rather than a random row and column how do I do this?

You forgot to format your code as code. You also didn't ask a specific question. What exactly is your issue? Player 1 has some random calls, player 2 doesn't. How did you try to adapt the code?

[Pranesh]

To my understanding you need an input from the user for the row and col variables for player2 instead of using randi function to generate random number between 1 and 3.

A possible work around could be using input() function similar to what is given below

function move = player2(gamestate) 
legal = false; 
while legal == false 
    Col=input ("enter col between 1 and 3"); 
    Row=input ("enter row between 1 and 3"); 
    
    if gamestate.board(row,col) == 0 
        legal = true; 
    end 
end 
move = zeros(3); 
move(row,col) = 1; 
End
