- You can manually rewrite the code to MATLAB. This link Functions in MATLAB explains functions in MATLAB.
- Have a look at this MATLAB Answers Post. You can directly call C++ code from MATLAB.

Hello! I have a code in c++, but it has functions and I don't know how to convert them to matlab, if someone could give me the correct way to transform it, it would be helpful.
#include<iostream>
using namespace std;
int index1;
char board[9] = {'*','*','*','*','*','*','*','*','*'};// Single array represents the board '*' means empty box in board
int isFull()// Board is full
{
for(int i =0;i<9;i++)
{
if(board[i]!='X')
{
if(board[i]!='O')
{
return 0;
}
}
}
return 1;
}
int user_won()//Checks whether user has won
{
for(int i=0;i<9;i+=3)
{
if((board[i]==board[i+1])&&(board[i+1]==board[i+2])&&(board[i]=='O'))
return 1;
}
for(int i=0;i<3;i++)
{
if((board[i]==board[i+3])&&(board[i+3]==board[i+6])&&(board[i]=='O'))
return 1;
}
if((board[0]==board[4])&&(board[4]==board[8])&&(board[0]=='O'))
{
return 1;
}
if((board[2]==board[4])&&(board[4]==board[6])&&(board[2]=='O'))
{
return 1;
}
return 0;
}
int cpu_won()// Checks whether CPU has won
{
for(int i=0;i<9;i+=3)
{
if((board[i]==board[i+1])&&(board[i+1]==board[i+2])&&(board[i]=='X'))
return 1;

return 1;

return 1;
}

Hello!
As per my understanding, C++ code needs to be converted to MATLAB code. I would suggest going through the following links:
Hope these solve your question.
