Hi,
I am having dificulties to read (load) a single row of a random size file. Please, how can I do it?
For ie. I would like to read all colums for the fisrt row of a csv file and create a string vector.
Thank you very much
Best Regards
Rafael

What difficulties are you having? What have you tried and why isn't it working?

Try fgetl. That's exactly what it does.

You would use a while loop to continue reading in the data a line at a time until you got to the end of file (feof).
while ~feof(fid)
tline = fgetl(fid);
disp(tline)
end
You would want to process each line and assign your data to a variable using indexing so as not to overwrite the previously saved values.
