How do you creat one large text file?
显示 更早的评论
So I have created these mini text files in matlab but I was wondering how do you create one large file with all these mini text files in it?

Saving them to one file initially would be more efficient. But let's try:
List = {'KuKaBand.txt', 'KaBand.txt', 'KuBand.txt', 'Noise.txt'};
OutFID = fopen(fullfile(tempdir, 'Total.txt'), 'w');
if OutFID == -1, error('Cannot open file'); end
for k = 1:numel(List)
InFID = fopen(List{k}, 'r');
if InFID == -1, error('Cannot open file'); end
InData = fread(InFID, Inf, '*uint8');
fclose(InFID);
fwrite(OutFID, InData, 'uint8');
end
fclose(OutFID);
So the strategy is: Open the resulting file for writing. Open each file for reading and append its contents to the resulting file.
[EDITED] The operating systems have some methods also. E.g. under Windows:
Str = sprintf('%s+', List{:});
system(['copy /b ', Str(1:end-1), ' Total.txt']);

i know that my answer is not making sense.i want you to be more specific in your question. how did you saved them?do you know all file names ? so you can save and load them with a for loop and changing the file name .
savefile = 'pqfile.txt';
p = rand(1, 10);
q = ones(10);
save(savefile, 'p', 'q')
in above code you can change savefile in a loop.so or in a similar manner for loading files.
