Load files from two different folders
显示 更早的评论
Hi,
I need to upload files from two different folders. I wrote this but it woking just from one folder. How can I add the second folder?
dirname=['D:\Shared\MATLAB\100min\BT']
cd(dirname)
filelist = dir([basename '*_BTlength.mat'])
Thanks

Do NOT use ADDPATH or CD or any other messing around with the MATLAB search path just for acessing data files.
All MATLAB functions which import/export data files accept relative/absolute filenames. Using relative/absolute filenames is more robust, more efficient, and easier to debug than messing around with CD or the search path. You should use relative/absolute filenames.
For example:
P = 'D:\Shared\MATLAB\100min\BT'; % got rid of the superfluous square brackets.
S = dir(fullfile(P,'*_BTlength.mat'));
for k = 1:numel(S)
F = fullfile(S(k).folder,S(k).name);
% do whatever you want with absolute filename F, e.g.:
D = load(F)
end

"I would like to add another folder"
It is easy to specify two paths, e.g.:
P1 = 'D:\Shared\MATLAB\100min\BT';
P2 = 'D:\Shared\MATLAB\100min-rep2\BT';
S = [...
dir(fullfile(P1,'*_BTlength.mat'));...
dir(fullfile(P2,'*_BTlength.mat'))];
for k = 1:numel(S)
F = fullfile(S(k).folder,S(k).name);
% do whatever you want with absolute filename F, e.g.:
D = load(F)
end
Alternatively you can use wildcards in the path name as well, e.g.:
P = 'D:\Shared\MATLAB\100min*\BT';
S = dir(fullfile(P,'*_BTlength.mat'));
for k = 1:numel(S)
F = fullfile(S(k).folder,S(k).name);
% do whatever you want with absolute filename F, e.g.:
D = load(F)
end

Use the addpath() function to add the path to your second folder to the working directory:
