Well something like this:
filename='tmp.txt';
fid=fopen(filename,'r');
if (fid==-1)
error('could not open %s for reading',filename);
end
nDataSet=fscanf(fid,'%d',1);
Data=cell(nDataSet,1);
for idx=1:nDataSet
nLines=fscanf(fid,'%d',1);
Data{idx}=fscanf(fid,'%f,%f',[2,nLines])';
end
fclose(fid);
You can access each data set using Data{dataSetNumber}. I generated some sample data set stored in a file called tmp.txt;(attached file). Here is the output.
>> Data{1}
ans =
1.0000 0
2.0000 0.9058
3.0000 0.1270
4.0000 0.9134
5.0000 0.6324
>> Data{2}
ans =
1.0000 0
2.0000 0.9058
3.0000 0.1270
4.0000 0.9134
5.0000 0.6324
1.0000 0
2.0000 0.9058
3.0000 0.1270
4.0000 0.9134
5.0000 0.6324
>> Data{3}
ans =
1.0000 0
2.0000 0.9058
3.0000 0.1270
If the input file really has ' at the begining and the end of the data then use the following code: (I have also attached tmp2.txt for you)
filename='tmp2.txt';
fid=fopen(filename,'r');
if (fid==-1)
error('could not open %s for reading',filename);
end
nDataSet=fscanf(fid,'%d',1);
Data=cell(nDataSet,1);
for idx=1:nDataSet
nLines=fscanf(fid,'%d',1);
tmpVar=strsplit(fscanf(fid,'%s',nLines),'''')';
Data{idx}=cell2mat(cellfun(@(c) str2num(c),tmpVar(2:end-1),'UniformOutput',false));
end
fclose(fid);
