Hi, I want to plot the same named data from different subfolders. The first level of folder is GM and in total 20 of them exists. Then 10 subfolders exist named #pga in each GM folder. I tried to modify and make the following code work but couldnt manage. Can anyone help?

(for g=1:2 for k=1:9

    eval(['load num2str(g),gm\',num2str(k/10),'pga\pga',num2str(k/10),'drift.out'])
end

for m=1:9 eval(['maxdrift(m,1)=max(pga0_',num2str(m),'drift(:,2));']); end maxdrift(10,1)=max(pga1_0drift(:,2)); end)

在 MATLAB Online 中打开

You can get the file information (name, folder, date, ...) of files within subfolders using the dir command and wildcards. e.g. if your are in the folder which contains the #gm folders then the command

files = dir('./*/*/*.out');

will return a struct of all *.out files within all the second level subfolders. You can then easily build a cell arrray of filenames and operate on them using cellfun:

filePaths = fullfile({files(:).folder},{files(:).name});
cellfun(@(x) disp(x),filePaths,'UniformOutput',false); % substitute disp by your function and add a return value to have catch your functions output in a cell
