Is fortran 90 or matlab better for simulating non-linear dynamics (Chaos)?

I am going to be simulating damped driven oscillators for my project and I was wondering if someone could give me a definitive answer on the matter. I know matlab is more of a 'tool' than a language so i'm thinking the maths behind damped driven oscillators might be easier to implement into fortran 90.
If someone could give me a few pros and cons for the two and maybe more specifically to the simulations involved with damped driven oscillators that would be great.

Thank you!
