[Plplot-general] plplot-octave usage

[Valery P. <pi...@is...>]

I've tryed to use  the plplot  from octave.  I have  debian-sid.
I found that plplot can not be used from octave with usual octave 
(gnuplot) syntax.  The simple receipt given in "Usage.octave"
like,
plplot_toggle;
x=-pi:0.1:pi;
plot(x,sin(x));

does not work;

The only method is  to  immitate the  way which was used  in octave 
examples
x*.m copied from c dir. Is it correct?

Why am I asking  this?

Let me explain a bit. I usually use plplot from yplot interface.
Recently I've upgraded plplot from 5.3.0-2 to cvs version (as was proposed
by apt)

I found that the following piece of yplot code (at the end of message)  
fails on this version of plplot but it works on 5.3.0-2.   At first 
moment I  wanted to test it from octave but realised that it is not as 
simple.

best rgds,
Valery
