As far as gnuplot's use of the term is concerned, that sentence directly 
contradicts the following two:

A file in that format is not in matrix form as understood by gnuplot.

Your data file format is not really usable by gnuplot as-is.  If at all 
possible, you should transpose it, i.e. make columns out of rows and 
vice versa.  Then a simple

     plot 'filename' using 1:3

will display what you want.
