Load from subfolders in directory

I have 429 matrices that needs to be stored in a subfolder, I call it CHARGING

I have 429 timetables hat needs to be stored in a subfolder, I call it TIMETABLES

The directory is the Desktop, where I have created the subfolders

I have issues with loading from these subfolders. I have tried

load 'TIMETABLES/Time1.mat' but that does not work

A follow up question is if it is possible to load the whole subfolder at once? So that I dont have to type load TimeXXX 429 times.

Please post the error message instead of the vague description "it does not work".

Error using load

Unable to read file 'TIMETABLES/Time1.mat'. No such file or directory.

Error in DRIVE (line 8)

load 'TIMETABLES/Time1.mat'

The error message tells you, that there is no folder called "TIMETABLES" inside the current directory or that the file "Time1.mat" does not exist. You can check this:

isfolder('TIMETABLES')
isfile('TIMETABLES/Times1.mat')

Are you working with Windows, Linux or MacOS?

What is the path of your Desktop folder?

Desktop = fullfile(getenv('USERPROFILE'), 'Desktop');
Data = load(fullfile(Desktop, 'TIMETABLES', 'Time1.mat'))

Or in a loop (see FAQ: Process a sequence of files)

FileList = dir(fullfile(Desktop, 'TIMETABLES', '*.mat'));
for iFile = 1:numel(FileList)
    File = fullfile(FileList(iFile).folder, FileList(iFile).name);
    Data = load(File);
    ... process or store your data here
end
