تشخیص زبان برنامه نویسی

با سلام دوستان عزیز
بنده برای پروژه برنامه نویسی برای درس Finite Element باید یک کدی که در زیر مینویسم رو در یک زبان مثل فورترن بنویسم اما متاسفانه نمیدونم این چه زبانی هست
یکی از دوستان گفتند که این هم خودش فورترن هست اما میخواستم از شما متخصصین عزیز هم این سوال رو بپرسم تا مطمئن بشم
با تشکر
