LISP is quite different from the languages we’ve looked at so far - but I will not give an introductory description, as there are plenty of resources on the Internet by better writers than me - instead I will look at how MTS LISP differs from more modern Lisps.
One of the reasons LISP did not become more popular for scientific computing was the perception that it was slower than FORTRAN. In this post I will compare the performance of the LISP and FORTRAN implementations on MTS using a simple problem.
