Macy" To: Hayden Rampadarath Cc: help at octave dot org Date: Wed, 11 Jan 2006 14:05:49 -0800 originally just made some sample files and looked at them... >> save -ascii "outgoingdataset.txt" variable1; ...then looked at it. but basically each of the five lines start with a pound sign and contain information like: 1 notes 2 variable name 3 type 4 rows 5 columns sample looks like this... # this is the data from run 21 only variable1 is used # name: variable1 # type: matrix # rows: 21 # columns: 1 23 33.3 75 . . . 34 ...but make certain you have at least more data than the number of rows you put in, or get an error. They look like this when I scooped from spread sheet. or, you could have... # this is the data from run 21 only variable1 is used # name: variable1 # type: matrix # rows: 1 # columns: 21 23 33.3 75 ... 34 ..but you may need tabs between them, can't remember - Robert - On Wed, 11 Jan 2006 21:14:07 +0000 (GMT) Hayden Rampadarath wrote: > hi, > can u tell me how to do the fake headers?? > > Hayden > > "Robert A.
