MATLAB: Load multiple files with a condition on the file name

cell arraysloadmatch a string in 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 ...
