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.

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
