Just type :
which -all adpmedian
I guess this function is not on your path. You will get the same error by typing:
aurelien(int8(4))
??? Undefined function or method 'aurelien' for input arguments of type 'int8'.
For more details see: Section 17: Undefined Function or Variable

which -all adpmedian
the result was :'adpmedian' not found.
means that 'adpmedian' not found, how can i add it , is it possible?
If you are sure that this function exists , localize it and use addpath command to add this function to your MATLAB path.

MATLAB does not have any function named adpmedian
I do not see any routines with a similar name.

That doesn't mean it's already programmed into MATLAB. You'll have to download it/rewrite it to somewhere on your MATLAB path.
