It is the right option for anything numerical and array-based. Any super-cool array-based feature that people see in MATLAB and Python was inherited from Fortran 90. Yes, that is true. Sadly, modern Fortran is treated quite unfairly within the field of computer science and engineering because of people's lack of knowledge of modern Fortran, which reminds me of the famous quote: "People hate each other because they do not know each other, and they do not want to know each other, because they hate each other".
