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

[mmm ssss]

which -all adpmedian

the result was :'adpmedian' not found.

means that 'adpmedian' not found, how can i add it , is it possible?

[Aurelien Queffurust]

If you are sure that this function exists , localize it and use addpath command to add this function to your MATLAB path.

[mmm ssss]

what do you mean by localize it ?

can you write what must i write to add it as a code line?

Answer 2

[Walter Roberson]

MATLAB does not have any function named adpmedian

I do not see any routines with a similar name.

[mmm ssss]

no , it is found.

i found it at 'Digital image processing using Matlab -Gonzalez and Woods book'at page 165.

[Sean de Wolski]

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