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

BTW: basf(cellfun(@(basf) isempty(basf),basf))=[]
Faster: basf(cellfun('isempty', basf))=[]

Thank you Jan for the answer!
It does make it faster! but do you have some ideas on how to make matlab load the files I need? like load just the basf files and then load just biog files?
thank you,

Hi Paulo,
Thank you for your answer! I tried both
load(char(basf)) and it gives me the following error message :??? Error using ==> char
Cell elements must be character arrays.
when I try load(basf{:}) it gives me the following error message: ??? Error using ==> load
Argument must contain a string.
I dont have any other ideas on how to make matlab load the files using the filenames contained in the cell arrays of basf and biog. Do you have other ideas? I would really appreciate your help :)
thank you

You cannot load more than one file in a single command. Please see the FAQ on handling multiple files.
