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?

Basically, I don't know how to do it...

Try fgetl. That's exactly what it does.

Hi,

Let's suppouse that we want the seccond or the n row of the file. How we can use this function?

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.
