Hello community.
I'd like to have your support to find a soluion.
I have several '.dat' files, I'm usinng mdfimport to export the variables I need and then save them into '.mat' format.
my code:
clear all;
clc;
[FileName,PathName] = uigetfile('*.dat','Select the .dat-file(s)','MultiSelect', 'on');
if class(FileName) == char('cell');
FileName = FileName';
end
if class(FileName)==char('char');
FileName = {FileName};
end
%========================================================================%
V = {
['EnvT_t']
['CtT_flgHeal']
['CtT_flgEna']
['Epm_nEng']
['CTM_Delta']
['CTM_Flag']
['CTM_Sum']
};
V=V';
for k=1:length(FileName)
%----------------------------------------------------------------------
progress = ['Working on file ' int2str(k) ' of ' int2str(length(FileName)) '...'];
disp(progress);
disp(FileName(k));
LoadPath = char(strcat(PathName, FileName(k)));
mdfimport(LoadPath,[],V, 'resample_1');
save(['@' num2str(k) '.mat'])
end
let's say I have below data:
Carr1.dat
Carr2.dat
Carr3.dat
Carr4.dat
my code will go trhoug each .dat file, will extract defined variables and then it will save it as follows:
@1.mat
@2.mat
@3.mat
@4.mat
how can I use save command to keep original file name? I'm looking to get this:
Carr1.mat
Carr2.mat
Carr3.mat
Carr4.mat
I've tryied different things but always get an error.
as always your feedback will be highly appreciated

for k = 1:N

LoadPath = fullfile(PathName,FileName{k});
mdfimport(LoadPath,[],V, 'resample_1');
SavePath = fullfile(PathName,FileName_mat{k});
save(SavePath)
end
