load multiple files with a condition on the file name

Hi everyone!

Im kind of new to matlab and I have the following problem: I have many files as .mat files with the following names, all in one folder. So what I want to do is to load all BASF files first and save them into a new BASF folder and then load all BIOG files and save them into a new BIOG folder.

data20091019_1BASF.DE

data20091020_1BASF.DE

data20091021_1BASF.DE

data20091020_1BIOG.DE

data20091022_1BIOG.DE

data20091101_1BIOG.DE

So far, this is what I have tried :

clear all

dirData=dir('*.mat');

filenames={dirData.name};

stringi=filenames;

for k=1:length(dirData)

    stringi=filenames;
    basf=regexp(stringi,'^dataOut(\d+)_1BASF.DE_rek.mat$','match');
    basf(cellfun(@(basf) isempty(basf),basf))=[]; %get rid of empty cell arrays 
    biog=regexp(stringi,'^dataOut_(\d+_1BIOG_p.DE_rek.mat$','match');
    biog(cellfun(@(biog) isempty(biog),biog))=[];
load(basf);
 end

The problem is when I try to load all the files included in the basf cell array it says " Argument must contain a string". So I dont know how to make matlab load all the files that contain BASF or BIOG in ther file names. Could you please help me? Thank you so much! Lourdes

    dfBASF = dir('*BASF.mat') ;
    for F = {dfBASF.name}
      curF = F{:} ; % current file
      disp(curF)
      movefile (curF, fullfile('BASF',curF) ) ; % test this first!!
    end
    df = dir('*.BIOG.mat') ;
    %  ... etc ...

Thank you Jos for your answer!

I tried it but it doesnt read the BASF files using the command '*1BASF.DE_rek', thats why I tried using regexp. Regexp can actually see which file names are BASF and which ones are BIOG but then I cant load the files.

You could (and should) modify the input to DIR to get your requirements! Something like '*BASF.DE.mat' might do ...
