removing an variable from a list of strings

so i have this list of string called str, it says cell in matlab. How can i remove any arbitrary variable from that list?

so i have

d = dir;
  str = {d.name};
  [s,v] = listdlg('PromptString','Select a file:',...
                  'SelectionMode','multiple',...
                  'ListString',str)

where str is a list of the files in the directory. I want to remove an arbitary variable in it (i dont want to delete from the directory, just remove it from str) how would i do that? Thanks
