The code works fine for single asterisk but for double asterisk error occurs. I have attached the code and output below.
CODE:
data='Demo 3.TXT';
FID=fopen(data,'rt');
numberoflines = 44;
for i=1:numberoflines
l = fgetl(FID);
if strcmp(l(1),'**')
target = l(2:end);
l = fgetl(FID);
exist Fid2;
if true(ans)
fclose(Fid2);
end
Fid2 = fopen(target,'w');
end
fprintf(Fid2,[l '\n']);
end
close all

Output:
Unrecognized function or variable 'Fid2'.
Error in untitled3 (line 16)
fprintf(Fid2,[l '\n']);

l = fgetl(FID);
if strcmp(l(1),'**')
fgetl returns a character vector (except at end of file)
l(1) will be a single character. A single character can never strcmp() to two characters.
