I find out the solution. The "cd" command used as a function then pass
in path string as argument. It works fine. So I adopt source block like
this:
#+headers: :var cwd=(expand-file-name "data/images/" (file-name-directory
(buffer-file-name)))
#+headers: :prologue "cd(cwd)"
#+begin_src matlab :session "*MATLAB*" :results output
% eval(sprintf("cd '%s'", cwd))
% eval(sprintf("cd('%s')", cwd))
% cd(cwd)
% returns the path to the current working directory.
pwd
#+end_src

#+begin_example
cd(cwd)
cwd='/Users/stardiviner/Org/Wiki/Computer Technology/Programming/Emacs/Emacs
Packages/Org mode/data/images/';
% eval(sprintf("cd '%s'", cwd))
% eval(sprintf("cd('%s')", cwd))
% cd(cwd)
% returns the path to the current working directory.
pwd
ans =
'/Users/stardiviner/Org/Wiki/Computer Technology/Programming/Emacs/Emacs
Packages/Org mode/data/images'
#+end_example
Really tricky for me. Hope helpful for some user.
