name_cell.mat

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}];

name_cell.mat

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

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
