Fullfile code gives error in other system

Hello Every one,

I have written the following code and it works well (reading some mat files from a folder, loading them and lator I do some calculations on the data),

V_deficit=dir('Vel_defcit_data/*.mat');
for i=1:27
    def_path = fullfile(V_deficit(i).folder,V_deficit(i).name);
    load(def_path)
end

but the problem is that when I send this exact code to someone else it doesnt work, we get the error:

Reference to non-existent field 'folder'.

Error in Vel_deficit

def_path = fullfile(V_deficit(i).folder,V_deficit(i).name);

I also asked to change the folder names to Vel_deficit as here, but still we get the error!

Thank you in advance for your help

Your "someone else" is using a MATLAB version older than R2016b:

https://www.mathworks.com/matlabcentral/answers/483844-dir-on-unix-does-not-return-folder-subfield#answer_395018

so the FOLDER field does not exist. Instead you can refer to the folder you specify:

P = 'Vel_defcit_data';
S = dir(fullfile(P,'*.mat'));
for k = 1:numel(S)
    F = fullfile(P,S(k).name);
    T = load(F)
    % do whatever with T
end
