At this point, which should I be using, a completely separate ob-racket
with the special
(racket . t)
or geiser for working with Racket? After some trouble I've got MIT Scheme
working with geiser and babel, and it seems to work with separate sessions
too. But this
#+BEGIN_SRC racket :results value :session *racket1*
(define two 2)
two ;; not output
(* two two two)
#+END_SRC
#+RESULTS:
: 8
gives me an answer, but starts no REPL, let alone a REPL session. Do I get
better functionality with geiser Racket? This is pretty good first try
#+begin_src racket :require math/matrix
;(require math/matrix)
(define A
(matrix [[1.00 0.00 0.00 0.00 0.00 0.00]
[1.00 0.63 0.39 0.25 0.16 0.10]
[1.00 1.26 1.58 1.98 2.49 3.13]
[1.00 1.88 3.55 6.70 12.62 23.80]
[1.00 2.51 6.32 15.88 39.90 100.28]
[1.00 3.14 9.87 31.01 97.41 306.02]]))
(define b (col-matrix [-0.01 0.61 0.91 0.99 0.60 0.02]))
(matrix-solve A b)
#+end_src
#+RESULTS:
: #<array #(6 1) #[-0.01 1.602790394502109 -1.613203059905556

but I miss having an actual live REPL session. BTW, there is no run-racket
