Software :: Octave (v3.2): Initialize Vector/matrix Without Screen Output

Oct 22, 2010

I have recently installed Octave on my desktop and I am very busy with RTFM ATM.However, this manual is huge and I could not find an answer to my problem. What I basically want to do is initialize a vector like

Code:

a=[]
for i 1:100
a = [ a i ]
endfor

Now my problem is that this will call the pager and I have to hit 'q' to get my prompt back. I know I can turn it off but the screen will still get cluttered with tons of output.Is there a way to initialize 'a' quietly without any screen output?

Slackware - 13.1 "VLC Failed To Initialize Sound Output Device" If Opened After Firefox

Aug 7, 2010

I've been having a recurring problem on Slackware64 13.1. If I open VLC (or any other media player available for Slackware) before I open Firefox, then my sound works 100% and there's never any problem, however, if I open Firefox first, and there happens to be a flash video loading, then any other media player (mplayer-plugin, Amarok or VLC) will fail to play sound. VLC tells me:

Quote: Potential ALSA version problem: VLC failed to initialize your sound output device (if any). update alsa-lib to version 1.0.24 or higher to try to fix this issue. Now, I'm happy to do that if it will actually fix the problem, though I'll have to figure out how seeing as I'm something of a n00b. The thing is that I've not really done anything to alsa except run alsaconf on my first boot, so I'm not sure if that's really the problem I've been using Slackware64 for a few months now, I'm on my first ever install and for the most part I'm loving it. Been working through the little things that have been annoying me, and for the most part I've managed to find solutions either by reading the Slackbook, by browsing LQ or by doing a quick Google search. However, I can't seem to find any reference to this specific problem anywhere and I'm not sure what I should do.

OpenSUSE :: Octave: Dmperm: Not Available

Mar 24, 2011

To anyone who got octave: The issue: whenever I call the function "dmperm", it gives me the following

Code:
error: dmperm: not available in this version of Octave
Typing dmperm(3) gives that. However, dmperm alone gives some instructions on how to use this. So it is seemingly there.

Getting the same thing? What I got is octave 3.4.0, on openSUSE 11.4 x86-64. I tried with the one in repos contrib, the one in packman, and the one in contrib:Factory. Same outcome. It could be that there is some missing dependencies that were not specified by the packager, perhaps. This older post Octave - General - dmperm mentioned some packages. Things I did not have I got installed: libumfpack5 umfpack-devel bison flex I could not install "umfpack" as such. It is a source package. It still does not work..........

Ubuntu :: How To Download Octave

Feb 23, 2010

I'm trying to download ocatve, and on the gnu.org website there are two file packages available. There is a "tar.gz" and a "tar.bz2". Are these two packages different versions of the same thing? Or are both of these packages necessary? And...if there is a difference, which package would be more suitable for Hardy 8.04?

OpenSUSE :: Octave: Error While Loading Shared Libraries

Nov 10, 2009

I installed octave in my OpenSUSE 11.2 KDE system from Yast. When I launch it with the command "octave" on my shell, this is the message I receive: "octave: error while loading shared libraries: liboctave.so: cannot open shared object file: No such file or directory". What's the problem? Is it a known problem to be solved in the 11.2 RC2 or I have to do something else?

Programming :: Out Of Range Vector Iterator?

Mar 20, 2011

I'm not really a C++ noob at all, but I am a little rusty at the moment. Still, I CANNOT figure out what is wrong with the following code. I'm using Visual Studio 2010.

Code: #include <iostream>
#include <fstream>
#include <vector>
#include <string>

[Code]....

I THINK I got all of the pertinent code. Anyway, it fails at the *** line. I CANNOT figure out why. If I modify it to be linein.size()-30, it STILL gives me an error. That makes zero sense.

Programming :: Passing The Char * Vector Argument?

Jun 19, 2010

I am trying to simulate a shell. So what I do is checking of having the parameters from standard input, suc as "/bin/ls -l /home/france/Documents", and then passing them to function execute, which at some point calls execvp(argv[0],argv)The problem is that I don't succeed in using these arguments, while if I call execvp(paramList[0],paramList) it works!!!! Where paramList is exactly what I would put on standard input, but defined statically.

Code:

#include<unistd.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>

Code:

ss << data[i];
}
string s_data = ss.str();

This works, but is there any better way to do it?

Slackware :: SVG Logo (GPL) Editable Vector Version?

Mar 3, 2011

I was fiddling with some svg icons and I needed a slack svg logo: looking on the propaganda page, I spotted this jpg that looked like a nice and clean candidate. So I fired up inkscape and tried to manually trace a (manageable) svg version out of it. Then I thought that maybe an editable vector version of it can be useful to someone else and, as asked by Pat, I release it here under the GPL. [URL]. (gotta say I haven't looked around if any other logo svg has been posted before, but, clicking on the "Click Here to Find Similar Threads" found this funny one )

Fedora :: Wobbling Screen On VGA Output?

Feb 12, 2011

first of all, during last few days I've visited this forum and asked for help, all in trying to fix the problem which I had. I failed to do so, and I am really frustrated now, as it is off very big importance.I'm huge fan of linux and fedora, so it kills me to have to boot to windows to do simple thing.

Problem: I bought DELL Vostro 3300. When I try to connect it through VGA(only output it has) to my monitor (tried different monitors, same effect), my screen wobbles. The higher the resolution -> higher the wobbling is. It is almost impossible to read text due to this. I attached extension which I recorded the wobbling (mp4 extension). Wobbling is even during linux startup, before xorg is loaded.

On lowest resolution wobbling is very little. It's same on different frequncies. I've tried different kernels but with no success.

What's important, it's not faulty hardware, since it works fine on Windows.

The problem has same characteristic as one mentioned here in buglist. In new kernel it's supposed to be fixed as I understand(?) but it's not for me.
