load files containing part of a string in the file name and the load that file

18 views (last 30 days)
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

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,

try with this litle change:
load(char(basf))
or this one:
load(basf{:})

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.
