How about introducing a struct *say, 's'), assigning data to it and saving 
using 'save("-text" ...);' ?

Or even without the struct ?

Here is an example from what I'm doing - contents of a files saved using 
'save("-text" ...);':

"# Created by Octave 3.0.5, Fri Jul 08 00:11:48 2011 IDT <address@hidden>
# name: accumulated_spectra
# type: struct
# length: 3
# name: MM
# type: cell
# rows: 1
# columns: 1
# name: <cell-element>
# type: complex matrix
# rows: 1
# columns: 589825
 (-78.97504911431373,-3.673076946111337e-14) 
...
".

It _does_ preserve rows and columns info.

  Sergei.
