MATLAB: Problem with looping through Folder finding pattern

Question

Hello everyone,

I am attempting to loop through a folder using this code:

files = dir(MyFolder);
Pattern = MyPattern % im searching for files that match a certain pattern
for i = 1 : numel(Myfolder) %loop through Myfolder
       % this next line below is where the error is coming from
       value = getfield(files,{i},'name') %iterate through each file in the structure, "files"
           % i did this because I need a string to use in strfind below
            if strfind(value,Pattern) %check to see if current file matches Pattern
                     f = fullfile(MyFolder,value) %construct fullpath
                      % do more stuff
     end
  end

Im not sure if this is the best approach, but the idea is to loop through MyFolder and construct a fullfile if a file matches pattern.

This is the error generated. It comes from getfield:

??? Index exceeds matrix dimensions.
Error in ==> getfield at 46
        f = f(index{:});
Error in ==> UI>pushbutton2_Callback at 252
value = getfield(files,{i},'name')

Any advice on a better approach would be great.

Answer 1

value=getfield(files(i),'name') or
value=files(i).name
