Since, you didn’t give any details, it’s hard to answer you. Though, I made a script which may fit your needs :

Vector3 scale;
Vector2 downPosition ;

void Awake()
{
    downPosition = new Vector2();
}

void Update ()
{
    if ( Input.GetMouseButtonDown( 0 ) )
    {
        downPosition = Input.mousePosition;
        scale = transform.localScale;
    }
    else if ( Input.GetMouseButton( 0 ) )
    {
        transform.localScale = scale + ( Vector3.right * ( Input.mousePosition.x - downPosition.x ) + Vector3.forward * ( Input.mousePosition.y - downPosition.y ) ) * 0.01f;
    }
}
