Ran in:
The following uses fscanf, fgets, str2num, and strcmp:
filename = 'file.txt';
fid = fopen(filename,'r');
counter = 0;
while counter < 2
str = fgets(fid);
if ~ischar(str)
break
end
if numel(str) > 1 && strcmp(str([1 2]),'--')
counter = counter + 1;
end
end
data = str2num(fscanf(fid,'%c'));
fclose(fid);
plot(data(:,2),data(:,3))
