How to plot data from different folders

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)

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
