Hello,
Looking help in saving same .mat file with prefix over loop.
Facing error with following script:
clear all
close all
d = uigetdir();
filePattern = fullfile(d, '*.mat');
file = dir(filePattern);
for k = 1: numel(file)
baseFileName = file(k).name;
fullFileName = fullfile(d, baseFileName);
% my code here
outputBaseFileName = sprintf('Edited_%s', baseFileName);
outputFullFileName = fullfile(file(k).folder, outputBaseFileName);
save(outputFullFileName,'Variable_1','-append');
end
Error I am getting is:
Error using save
Unable to write file 'myPath\Edited_myFileName.mat'
No such file or directory.
Error in Untitled (line 29)
save(outputFullFileName,'Variable_1','-append');

You can cerate a dummy text file where you want to save your files, then compare its path+name to the output of outputFullFileName

x=load(fullFileName)
x.Variable_1 = x.Variable_4./x.Varibale_5;
outputBaseFileName = sprintf('Edited_%s', baseFileName);
outputFullFileName = fullfile(file(k).folder, outputBaseFileName);
save(outputFullFileName, '-struct', 'x');
end

Your Edited .mat file does not exist, so you must create it. Check to see if it exists, if it does, append. If it does not, create it.
clear all
close all
d = uigetdir();
filePattern = fullfile(d, '*.mat');
file = dir(filePattern);
for k = 1: numel(file)
% my code here
outputFullFileName = fullfile(file(k).folder,sprintf('Edited_%s', file(k).name));
if exist(outputFullFileName,'file') % file exists
save(outputFullFileName,'Variable_1','-append');
else % file is new since you made it "edited", and needs created
save(outputFullFileName,'Variable_1');
end
end
