Re: How to plot the sum of two vectors

[Michael Goffioul]

It seems gnuplot is not installed on your system. Gnuplot is used to
do plotting stuffs. Install gnuplot and try again.

Note also that you're using version 2.9.12 of octave, which is rather
outdated. The current stable version is 3.0.0. You should consider
upgrading your system.

Bye,
Michael.
