Difficulties to plot the results

Bonjour,

Octave has problems plotting the results. Only 1/4 processor works with
Octave. So, we can understand that Octave is slow and plotting is
difficult.

Idea to improve?

Regards,

Michel

Bonjour,

Plotting works well, though it is fair to say the documentation is not
of the best.

If you have a CPU with 4 processors Octave will only use 1 of them
hence it will appear to use "only 1/4 processor'. Is this your
problem?

No. If used correctly it is not slow. As with any interpretive
language avoid loops wherever possible. The Octave language is very
powerful and gives many opportunities to avoid loops.

Yes, plotting is difficult generally because there are so many types
of plot and options for each type.

Please be more precise about the problems you are experiencing.

*My problem is that octave misuses the PC resources. 1 processor activity is
at a plateau at 25% while the other ones are about few %.*

Yes, plotting is difficult generally because there are so many types

*In fact, they are many points to plot around 1e6 points.*

*I don't remember exactly but it seems to me that during the installation,
there was a message about java and the consequences on Octave's
performance.*
