Matlab problem:

I need to create a move for the computer in the tic-tac-toe game, which the computer will never loses. plz modify the codes below to create a script for this.

Hint: you need to put some sort of strategy into the code.

Main script

(Below is the moving code, plz modify this code to create a move which the computer will never lose in the tic-tac-toe game)
