I'm trying to find a two words (DATA & END ) repeated many times in a .txt file how I can get their positions or in any lines they are exist because I want to bring the numbers which are between these two words
this is a part of the file
-- Coefficient of friction (for calculation of temperature) -- SchmierTyp 0:Oil 1:Grease 2:Dry :TABLE FUNCTION ReibKoef INPUT X SchmierTyp TREAT
DATA
1 2 3
0,01 0,02 0,03
END
-- Coefficient of friction (for calculation of temperature) -- SchmierTyp 0:Oil 1:Grease 2:Dry :TABLE FUNCTION ReibKoef INPUT X SchmierTyp TREAT
DATA
1 2 3
0,01 0,02 0,03
END
and I'm trying to do this by typing
haystack = fopen('h1.dat','r');
needle = 'DATA';
line = 0;
found = false;
while ~feof(haystack)
tline = fgetl(haystack);
line = line + 1;
if ischar(tline) && ~isempty(strfind(tline, needle))
found = true;
break;
end
end
if ~found
line = NaN;
end
Thanks in advance

At first glance, your code looks correct. It will find the first line that contains 'DATA'. So what exactly is the problem you are having?

You just have to extend your if-structure:
if ischar(tline)
if found
if strcmpi(tline,'END')
found=false;
else
mydata(end+1,:)=str2num(tline);
end
else
if strcmpi(tline,needle)
found=true;
end
end
end
I cannot test this code right now, but it should at least serve well as starting point. Of course, you have to initialize mydata at the beginning (mydata=[];).
