open some .mat files (whose names are saved inside a cell)

Hi! I need to open some .mat files (whose names are saved inside the 'name_cell' cell).

I tried this way but, of course, it saves them all with the same name, overlapping them.

load name_cell.mat
folder = pwd;

for K = 1:height(name)

    % Load file .mat
    file = load(fullfile(folder,name{K,1}));
    file = file.original_name;     % all files are originally named 'original_name'

end

I would like to open them all with that specific name inside 'name_cell'.

Also, I need to save those open files in a single cell, like this:

matrix_cell = [{file_1};{file_2}];

Where C is your cell array of filenames, and assuming exactly one array is saved in each MAT file:

D = C;
for k = 1:numel(C)
    S = load(C{k});
    D{k} = S.original_name;
end

Thank you for your reply, but the code does not work.

Unable to perform assignment because the left and right sides have a different number of elements.

Also consider that the .mat files (cells) in the 'folder' (from which I have to read them) are saved with names like 'file_1', 'file_2' etc. They take the name 'original_name' when I import them like this:

load file_1.mat %workspace: file_1 -> original_name

"but the code does not work. Unable to perform assignment because the left and right sides have a different number of elements."

Please upload a MAT sample file by clicking the paperclip button.

Note that I updated my answer to follow the approach you used. Please test it again.

Hi @Stephen23. I tried the code again and it works with the preceding code:

D = C;
for k = 1:numel(C)
    S = load(C{k},'original_name');
    D(k) = struct2cell(S);
end

I did something wrong in copying and pasting. But I need to read the .mat files from a 'folder' other than pwd. How can I modify the code you gave me?

"But I need to read the .mat files from a 'folder' other than pwd."

Provide the absolute/relative filepath and use FULLFILE:

P = 'absolute or relative filepath to where the files are saved';
D = C;
for k = 1:numel(C)
    F = fullfile(P,C{k});
    S = load(F,'original_name');
    D(k) = struct2cell(S);
end
