Quoting Ivan Adzhubey <address@hidden>:

What is the best way to read vector/matrix data from a file? The
i.e., one vector per line, comma-separated vector elements. The idea is to
read the whole block of data in and then loop over it (creating vector
views?) doing calculations.

Hi Ivan,

You are right that GSL has a very minimal I/O.  It isn't so much for reading
data in <your> format, as providing a quick way to dump stuff to file and then
read it back.  The idea is to use routines like getline(), strtod(), strchr(),
scanf() and so on to get the job done.
