Hi! I have a question about how can I save a loop outputs. I want to write the output values of a large series of files on a separate line on text.txt. The problem is it only works with the first one, but it doesn't work with the rest. Is there something wrong?
myPath = 'C:\EX\';
a= dir (fullfile(myPath,'*.DIM'));
fileNames = { a.name };
% Rename files
for k = 1:length(fileNames)
newFileName = [fileNames{k}(1:2) fileNames{k}(4:6) '.txt'];
movefile([myPath fileNames{k}], [myPath newFileName]);
end
filePattern=fullfile( myPath,'*.txt');
txtFiles= dir(filePattern);
for k = 1:length(txtFiles)
baseFileName=txtFiles(k).name;
fullFileName= fullfile(myPath,baseFileName);
fid=fopen(fullFileName, 'r');
for i = 1:18
m{i} = fgetl(fid);
end
result2 = m{18};
result2b= result2([12:19]);
fid=fopen(fullFileName, 'r');
for i = 1:30
m{i} = fgetl(fid);
end
result3 = m{30};
result3b= result3([12:19]);
fid=fopen(fullFileName, 'r');
for i = 1:31
m{i} = fgetl(fid);
end
result4 = m{31};
result4b= result4([12:20]);
fid=fopen(fullFileName, 'r');
for i = 1:19
m{i} = fgetl(fid);
end
result5 = m{19};
result5b= result5([12:20]);
text= {baseFileName, result2b, result3b, result4b, result5b};
final= [Fields'; text];
end
I've read about fprint command and I've tried but it doesn't work at all. Really thanks in advance!
EDIT:
I added a screenshoot about my variables. Is it possible because of the txtFiles is wrong?

filePattern = fullfile( myPath,'*.txt');
txtFiles = dir(filePattern);
output = cell(length(txtFiles), 5);
for k = 1:length(txtFiles)
baseFileName = txtFiles(k).name
fullFileName = fullfile(myPath, baseFileName );
fileData = fileread(fullFileName);
fileCell = regexp(fileData, '\n', 'split');
result2 = m{18};
result2b= result2([12:19]);
result3 = m{30};
result3b= result3([12:19]);
result4 = m{31};
result4b= result4([12:20]);
result5 = m{19};
result5b= result5([12:20]);
output(k, :) = {baseFileName, result2b, result3b, result4b, result5b};
end

You are not closing the files you open.

Now after your changes we do neither know your program, nor your expectations, nor the occurring error message or whatever "doesn't work" exactly mean. How could we guess an improvement?
