how to make a script that plots all data loaded from to different repositories?

hello! I must plot alot of data, so I would like to know if there is a way how to make a script that loop over all the data files in two different repositories and when the files have a similar number at the end of their names just plot them together. I hope I have made myself clear? any suggestions are very welcomed! thank you!

You can use fileparts() to separate the directory and extension from the file specification. After that, the best way to determine the file number (for matching) would depend upon how the file names are structured.

I have written the following code, and I have made the files in both repositories with the same name, I get the data from the first repository but I get the error unable to read file from the second repository. any suggestions ???!!

   addpath('..\data\f1files')
addpath('..\data\f2files')
direction1  = '..\data\f1files'
direction2  = '..\data\f2files'
filepattern = fullfile(direction1,'*.mat' );
theFiles    = dir (filepattern);
for i=1: length(theFiles)
    baseFileName = theFiles(i).name;
    fullFileName1 = fullfile(direction1,baseFileName);
    fullFileName2 = fullfile(direction2,baseFileName);
    F1= load (fullFileName1)
    plot(F1.fdata);
    hold on;
    F2= load(fullFileName2)
    plot(F2.fdata);
    legend('f1' , 'f2');
end

Change

    hold on;
    F2= load(fullFileName2)
    plot(F2.fdata);
    legend('f1' , 'f2');

to

    if exist(fullFileName2, 'file')
      hold on;
      F2 = load(fullFileName2)
      plot(F2.fdata);
      legend('f1' , 'f2');
      hold off
    else
      legend('f1');
    end

    title(baseFileName);
    pause(1);

but why the code fails in loading the data from the second repository ??I mean I only get the data from the first repository ploted!!! any suggestions ??!!

You asked "when the files have a similar number at the end of their names just plot them together" . Perhaps the file names in the two directories are not identical, just matching in some part of interest to you. You should post a file name from the first directory and the corresponding file name from the second directory.

problem solved! just add the following line to the code, thank you very much !

filepattern2 = fullfile(direction2,'*.mat');

In what way does that help? You do not use filepattern2 in your code?
