sorting list of structures in a structure

I have a list of structures in a structure.

I tried this:

%% Load data

matpath = 'C:\Users\..;

mydata = dir(fullfile(matpath ,'*.mat'));

full_file_names = fullfile(matpath,{mydata.name});

for n = 1:length(mydata)

mydata(n).data = load(full_file_names{n});

active_flow(n) = mydata(n).data;

end

The mydata(n) structure is ordered. To access of the structure I tried "active_flow(n) = mydata(n).data". But my active_flow is NOT longer ordered.

Please how can sort "active_flow" structure. See an attached screenshot of mydata structure.

"The mydata(n) structure is ordered... But my active_flow is NOT longer ordered."

There is nothing in the code that you show that changes the order.

It is unclear what the problem is, because you did not explain or show either the "wrong" order nor the "right" order. If you want the filenames in alpha-numeric order then you could DOWNLOAD the function NATSORTFILES:

P = 'C:\Users\..';
S = dir(fullfile(P,'*.mat'));
S = natsortfiles(S); % DOWNLOAD if you want alpha-numeric order of filenames
for n = 1:numel(S)
    F = fullfile(S(n).folder,S(n).name);
    S(n).data = load(F);
end
active_flow = [S.data] % optional, if all MAT files contain the same variable names

Hi Stehen,

Thank you for your response.

I download the 'natsortfiles' function and to my file path but I still receive this error:

'natsortfiles' is not found in the current folder or on the MATLAB path, but exists in:

Change the MATLAB current folder or add its folder to the MATLAB path.

which folder the function suppose to be in?

Enter the command 'cd' in the command window and see the output.

[Stephen23]

"which folder the function suppose to be in?"

It is exactly as with your own files: either in the current directory (simpler) or on the MATLAB Search Path:

Thank you Stephen. It has worked.
