file name recognition

I have a directory wich can containn files.A XOR files.B

I need to write code to dell if the extension is A or B and based on that assign myfunct=AA() or myfunct=BB()

any suggestions appreciated?

Answer 1

[PATHSTR,NAME,EXT,VERSN] = FILEPARTS(FILE) returns the path, filename, extension and version for the specified file. FILEPARTS is platform dependent.

since my directory only contains one type of files. How would I tell to grab, say, first file and and equate it to 'FILE'

filelist = dir();
filelist([filelist.isdir]) = [];  %remove . and ..
for K = 1 : length(filelist)
  [pathstr, name, ext, versn] = fileparts(filelist(K).name);
  if strcmp(ext,"A")
    myfunct = AA();
  else
    myfunct = BB();
  end
end
