printing to console from C/Fortran

Hi All,

What is the proper way of printing to the console from a C/Fortran program
called from Octave?  Is printf ok?

(The reason I am asking is that when I read the R documentation, there it is
mentioned that printf will not reliably print to the console and other
function is
provided. I am releasing the same code for both R and Octave.)

Thanks!
-Matyas

Re: plotting the data given below

Thanks. It works.
 
 



Hi,
As of Octave 3.4.3 the function plot does not accept sparse arguments.
You have to flatten (or what-ever-is-called) your matrix before
plotting:

plot ( X, full(q), 'y*', "markersize", 6)

Re: Providing Entire Contents of the File

martin_helm,
I have added the @ before glycODE, and remove x =[]. It works. But *0*
should be changed into *model.ststmet.* then the simulation finally succeed.
Thank you for your help.

Shouldn't that be 

x = lsode(@glycODE,0,timeRange) 

instead and simply remove the  x=[] from your glycODE after you changed 
that.

This works perfectly!! The 3 "bugs" are gone!! It only looks like octave 
became a bit slower, but it might simply be my own impression...

Considering that the "bugs" are gone, I think it is not necessary to 
make a bug report for pcolor, right?

Thanks a lot for your help, you really made my day!

Cheers, Ismael.

One motivation of the fltk backend is too allow octave to have more control. This is a good example where
gnuplot does one thing and Matlab does another.

There is no need for  a bug report unless you can show that gnuplot is able to do what is needed.

Glad this worked for you!

Is there a way to get input data from network resources and process it from Octave

Hello help-octave <at> octave.org

I have a quick question. I need to know if there already exists a tool
or script that works with octave th..

Here is the thing..I have different endpoint agents that generate a
metric. (Example temperature) I manually grab these metrics through
the network and input them in an octave script.

Im planning to develop a tool in python that collects those metrics
remotely and invoke octave to process them in batch so the process is
automated.

Before i begin i want to know if there exists today a tool that
performs more or less that task?

thanks in advance

Manuel

Have you looked at the sockets package?

Oh, btw, I forgot, you might also be interested in Pytave:

    https://code.launchpad.net/pytave

It can run Octave commands and returns numpy objects.

Depending on what you're doing, numpy alone might also be sufficient.

sombrero doesn't show (fltk)

The following lets me see the first, but not the second figure:

octave> set(0, "defaultfigureunits", "normalized") ;
octave> plot(rand(2,2));
octave> sombrero;

Any ideas why?

M.

I thought this had been fixed.

	graphics_toolkit fltk
	figure (1)

These commands display an empty figure as expected.

	set (1, "units", "normalized")

Changing the units to normalized results in a very small figure in the UL of the screen.

The units conversion for figures is not working correctly. I've filed a bug report.
