#+begin_src maxima :var s=4 :results silent

Pass a string
#+begin_src maxima :var fun="sin(x)" :var q=2 :results silent
print(diff(fun, x, q))$
#+end_src

* Graphic output
Graphic output
#+begin_src maxima  :var a=0.5 :results graphics :file maxima-test-sin.png
plot2d(sin(a*x), [x, 0, 2*%pi])$
#+end_src

#+begin_src maxima  :results graphics :file maxima-test-3d.png
plot3d (2^(-u^2 + v^2), [u, -3, 3], [v, -2, 2])$

** Use the ~draw~ package
This test exercises the ~:graphics-pkg~ header argument.
#+begin_src maxima  :var a=0.5 :results graphics file :file maxima-test-cos.png :graphics-pkg draw
draw2d(explicit(cos(a*x), x, -%pi, %pi))$
#+end_src

* Output to a file
Output to a file
#+begin_src maxima :file maxima-test-ouput.out
for i:1 thru 10 do print(i)$
#+end_src
* List input
  :PROPERTIES:

Simple list as an input
#+begin_src maxima :var a=(list 1 2 3) :results silent :results verbatim
print(a)$
#+end_src

#+begin_src maxima :var a=(list 1 (list 1 2) 3) :results silent :results verbatim
print(a+1);
#+end_src

* Table input

Matrix

* LaTeX output
#+begin_src maxima  :exports both :results latex :results verbatim

tex(ratsimp(diff(%e^(a*x), x)));
#+end_src

#+results:

* Batch
Exercise the ~:batch~ header argument. These tests are also defined in ~testing/lisp/test-ob-maxima.el~. The test name is name of the ~ert~ test.

#+name: ob-maxima/batch+verbatim
#+begin_src maxima :exports both :results verbatim :batch batch

integrate(exp(-t)*t^z, t, 0, inf));
#+end_src

#+begin_src maxima :exports both :results verbatim :batch batch :cmdline --quiet
