pen drive read file

addpath(genpath([H:\D\codes\scene understanding\codetsu\codetsu,'\codetsu'])); savepath; Undefined function or variable 'H'.

Didn't enclose the path in quotes so Matlab's trying to interpret it.

addpath(genpath(['H:\D\codes\scene understanding\codetsu\codetsu','\codetsu']));

save(FileName, Variables). Specify the full path of your file, e.g. 'd:\mydoc\file.mat'

Hello Yanagawa,

You should use for loop for that operation to get one by one each folder path.

Try this (also detects all folders in a parent folder). You can create a cell array of folder names you wish in folders variable.

Main_Folder = 'C:/users';
files = dir(Main_Folder);
idx = [files.isdir];
folders = {files(idx).name};  % this can be your  folders = {'Faces','NonFaces'}
% If You can also only define folders you don't need above code. 
subfolder = cell(1,numel(folders));
for i = 1:numel(folders)
 subfolder{i} = fullfile(Main_Folder, folders{i})
 cd(subfolder{i})  % Change your directory to i'th subfolder
 % do what you want (your file extraction, etc) in that current directory
end
