save path

Hello,

I have a problem with saving files in different paths and I am very thankful for your help.

Suppose there is a fix path:

path = 'D:\folder_1\folder_2';

If I wanna save a data set in the same path I would write:

save(fullfile(path,'FILE_NAME.MAT'));

However, base upon each data set I need to save them in different subfolders of folder_2 such as dataset_1 in folder_2A, dataset_2 in folder_2B, etc. Note that the base PATH is always the same. How can I do that?

Thanks so much :)

Something like that should do:

base_path = 'D:\folder_1\folder_2';

% You can also use dir to get the list of the subfolders
subfolder{1} = 'folder_2A';
subfolder{2} = 'folder_2B'; % etc...

fname{1} = 'dataset_1.mat';
fname{2} = 'dataset_2.mat'; % etc...

for k = 1:length(subfolder)
    save(fullfile(base_path,subfolder{k},fname{k}));
end

HTH,

If there is a pattern to fname entries then you can compute them. For example, for folder_1A folder_1B folder_2A folder_2B ...

for K = 1 : ...
  series = floor((K-1)/2) + 1;   %1,1,2,2,3,3,...
  AB = char('A' + mod(series-1,2));  %ABAB
  this_folder = sprintf('folder_%d%s', series, AB);
  ...
end

The following code creates a matfile inside a folder of folder.

But, How to save a vector into the output_1.mat file?

I have a vector formed inside a loop which I should save as output_1.mat

How to do that?

   for s=1:length(subfolder) % 2 here
    for ss=1:length(subsubfolder) % 7 here
        for sss=1:length(a) %20 here
        fname{sss} = sprintf('output_%d.mat',a(sss));
        ffname{sss} = sprintf('feat_%d.mat',a(sss));
        save(fullfile(base_path,subfolder{s},subsubfolder{ss},fname{sss}),out);
        save(fullfile(base_path,subfolder{s},subsubfolder{ss},ffname{sss}),Feat);
        end
    end
end

 save( fullfile( base_path, subfolder{s}, subsubfolder{ss}, 'output_1.mat'), 'YourVectorNameGoesHereAsAString');
