Hello,

I need to automatically load many files whose filenames have a date (MMDDYY) in the end. Some files might be replaced later on by other files with a different date only. e.g.

a_b_c_d_111709 will be replaced by:
a_b_c_d_080310

I need to keep opening the file regardless of the date in the end of the filename. Any ideas how can I use "load" or any other command to do this?

Thanks,

You use dir along with a wildcard *

something like

loadedFiles = dir('*.dat')

then you might need a few more lines to read in each file individually depending on file type

See question 4.12 in the newsgroup FAQ.

Thanks guys,

I came up with a solution using regexpi:

locat = uigetdir('','Select the folder where the files are');
filenames = dir([locat '/*.mat']); aux = numel(filenames);
filenames = struct2cell(filenames);
filenames = filenames(1,1:aux);

% ftarg = target file

for i = 1 : aux
fdir = char(filenames(i)); fdir = fdir(1:regexpi(fdir,'|.mat')-1);
x = regexpi(fdir,'\d+'); x = max(x);
dmdate = fdir(x:end); fdir = fdir(1:x-1);
if strcmpi(ftarg,fdir) == 1
return
end
end

thx
