====Octave - installing additional packages====
On http://octave.sourceforge.net/packages.html you can find all packages for Octave.<br>
You can download all packages in a single file or you can take the ones you want.<br>
After downloading the package install it by typing '''pkg install <package name and path>''' like '''pkg install signal-1.0.7.tar.gz'''.
If you are running Windows Vista it is important that you start Octave with "Run as administrator" otherwise installation will fail with errors like 'couldn't create installation directory'.
If you install signal-1.0.7.tar.gz you also need to get a previous version of resample.m, there is a bug in the newest version. It returns "error: invalid row index = xxxxxx" if you try to use it.<br>
You can get the previous version of resample from:
* http://octave.svn.sourceforge.net/viewvc/octave/trunk/octave-forge/main/signal/inst/resample.m?revision=4585
Overwrite:
* "C:\Program Files\Octave\share\octave\packages\signal-1.0.7\resample.m"
If you are running Windows Vista remember that you need to be running as as administrator to overwrite files below 'C:\Program Files'. If you just try to change the contene of resample.m with an editor not started as "Run as administrator" it will save your file in "C:\Users\<username>\AppData\Local\VirtualStore\Program Files\Octave\share\octave\packages\signal-1.0.7".

On http://octave.sourceforge.net/packages.html you can find all packages for Octave.
You can download all packages in a single file or you can take the ones you want.
After downloading the package install it by typing pkg install <package name and path> like pkg install signal-1.0.7.tar.gz. If you are running Windows Vista it is important that you start Octave with "Run as administrator" otherwise installation will fail with errors like 'couldn't create installation directory'.

If you install signal-1.0.7.tar.gz you also need to get a previous version of resample.m, there is a bug in the newest version. It returns "error: invalid row index = xxxxxx" if you try to use it.
You can get the previous version of resample from:

Overwrite:

  • "C:\Program Files\Octave\share\octave\packages\signal-1.0.7\resample.m"

If you are running Windows Vista remember that you need to be running as as administrator to overwrite files below 'C:\Program Files'. If you just try to change the contene of resample.m with an editor not started as "Run as administrator" it will save your file in "C:\Users\<username>\AppData\Local\VirtualStore\Program Files\Octave\share\octave\packages\signal-1.0.7".
