Is there friend know Emacs Org mode and Matlab here?
I try to save Matlab plot into image file in another path instead of
current working directory. Like
bellowing code:
#+headers: :var cwd=(expand-file-name "data/images/" (file-name-directory
(buffer-file-name)))
#+headers: :prologue "eval(sprintf("cd '%s'", cwd))"
#+headers: :epilogue "saveas(gcf,'matlab-plot-demo2.png'); close(gcf);"
#+begin_src matlab :results graphics file link :dir "data/images" :file
"matlab-plot-demo2.png" :session "*MATLAB*"
bar([1 11 7 8 2 2 9 3 6])
#+end_src
#+RESULTS[(2023-04-13 00:09:01) c5fc0d36b27e75610664ee69ae618649637e45d9]:
[[file:data/images/matlab-plot-demo2.png]]
But Matlab command "cd" does not work correctly in upper code method.
Currently I come up with two solutions:
solution 1
#+begin_src matlab :results graphics file link :file
"data/images/matlab-plot-demo2.png" :session "*MATLAB*" :var
img="data/images/matlab-plot-demo2.png"
bar([1 11 7 8 2 2 9 3 6])
% saveas(gcf, 'data/images/matlab-plot-demo2.png')
% saveas(gcf, img)
disp(img)
close(gcf)
#+end_src
#+RESULTS[(2023-04-13 12:08:35) b87e1d8687e33acc089ea7374829c4d41e3dd0e4]:
[[file:data/images/matlab-plot-demo2.png]]
solution 2
#+headers: :var cwd=(expand-file-name "data/images/" (file-name-directory
(buffer-file-name)))
#+headers: :prologue "eval(sprintf("cd '%s'", cwd))"
#+headers: :epilogue "saveas(gcf,'matlab-plot-demo2.png'); close(gcf);"
#+begin_src matlab :results graphics file link :dir "data/images" :file
"matlab-plot-demo2.png" :session "*MATLAB*"
bar([1 11 7 8 2 2 9 3 6])
#+end_src
#+RESULTS[(2023-04-13 00:09:01) c5fc0d36b27e75610664ee69ae618649637e45d9]:
[[file:data/images/matlab-plot-demo2.png]]
Both does not work.
If you got a workable solution, please help me, Thanks very much.
