how save diplayed data?
显示 更早的评论
hi,
i have the following code:
fid=fopen('webscopG.txt');
for j=1:100000
tline = fgetl(fid);
i=i+1;
if ~ischar(tline), break, end
disp(tline);
end
fclose(fid);
this code will display tline as array, and that what I need . But how I can save this array of tline.
thanks

Save it how? In a different text file? In a .mat file?

If you are unable to modify that source, then consider the diary command, or consider executing that source within evalc() and writing out the characters you get back from evalc().
Much better would be to follow IA's suggestion of writing to a file within the loop itself. fopen(), fprintf(), eventually fclose()

fid=fopen('webscopG.txt');
outfid=fopen('webscopOut.txt','wt');
for j=1:100000
tline = fgetl(fid);
if ~ischar(tline), break, end
i=i+1;
fprintf(outfid, '%s\n', tline);
end
fclose(fid);
fclose(outfid);

I don't see why Walter's code wouldn't work. Maybe you should just try this:
copyfile('webscopG.txt', 'webscopG_Copy.txt');
After all, you're simply just transferring lines.

Huda, notice that tline is fprintf()'d within the loop, not after the loop.
If you want a variable to contain all of the lines after the loop, store tline into a cell array.

if (i >= RangeStart) && (i <= RangeEnd); fprintf(....); end

fid=fopen('webscopG.txt');
for j=1:100000
tline{i} = fgetl(fid);
i=i+1;
if ~ischar(tline),
break,
end
disp(tline);
end fclose(fid);
does that work?

No, you cannot have "fclose" in the same statement as "end".
