In this context you can interpret "e" as meaning "ten to the power of".
 For example, your output "-1.26e+001" is equivalent to -1.26*10^1 or
-12.6.  Similarly, "3.45e-3" would be the same as 0.00345.

Two related points that may be of interest:
1. The use of "e" described above applies not only to reading output,
but can also be used when entering data (e.g., "x=1e4" is the same as
"x=10000").
2. You can use the "format" command to specify how your results are
printed to the screen.  (Type "help format" at the octave prompt for
more details.)

Hope this helps.
