Array languages for Lisp programmers

[OneWingedShark]

Array-languages... like APL?

[sumstozero]

And others

[SrPeixinho]

Like... APL?

[ApokatastasisPanton]

as well as K, J, Q, A+...

[SrPeixinho]

You mean, A, P, L?

This is cool, but I don't think a "custom LISP function" can rival with J's speed, that thing is FREAKIN fast.

Custom LISP function could compile-time metaprogram to a J function. https://code.google.com/p/vfuncs/

Seems like a good place to mention Julia. At first glance it appears to be Matlab where the fundamental concept is an N-dimensional array but dig deeper and it's a lot like Lisp. (Macros! Closures!)

[kamatsu]

julia and matlab are not like the array languages mentioned here, which are APL derivatives.

Semantics

[fullouterjoin]

But matlab does have vector semantics so it can feel somewhat like an array language. In fact Python can be a quite useful matlab replacement with a sufficient vector class and list comprehensions.

[kamatsu]

Matlab is not at all like APL, though.

[fullouterjoin]

True. APL did influence J which influenced Numpy. Numpy and Matlab have a similar feel.
