Perhaps this will get you started.  I generally put a '#' comment
character at the begging of comment lines as shown in the example
data file.  Then it is easy to use the .m file shown here to do
something close to what you are asking for.  There are certainly
methods within octave to read files line by line and decipher what
each line contains but the attached is simple, and quick so this
is what I will often do.

Others will undoubtedly provide you with much better solutions
but hopefully this will get you started.

Talk to you later.  Ron.
