Suppose your file has a header like
radiation, temperature, voltage
data....
Then your program would get the header with
fid = fopen(yourfile);
currentline = fgetl(fid); % gets the first line of the file
col = 0;
nextind = 1;
while (currentline >0)
col = col + 1;
[parm{col}, count, errmsg, nextind] = sscanf(currentline(nextind:end),'%s,');
end
parm is a cell array that contains all your header parameters.
