I recently had to install Octave's version of Matlab's Optimization Toolbox to perform a nonlinear least-squares curve fit. I thought I'd archive the process here, for future use.
I am doing this on a Ubuntu Desktop, but the process ought to be similar on other Linux machines.
Installing Packages
1. Install the package "liboctave-dev" using the GUI Software Center, Synaptic Package manager, or the command line as:
3. Open an Octave session in the location where you saved the zipped files. At the prompt type:
> pkg install struct-1.0.11.tar.gz
> pkg install optim-1.4.1.tar.gz
If there are no errors, then the package is successfully installed.
UPDATE October 2018: With a newer Octave installation [ > 3.4.0], you can merge the download and install steps by a command like:
> pkg install -forge struct
It does the downloading, installing, and cleaning up for you.
Loading Packages
When you want to use a function from a package in an Octave program, you first have to load the package name (not the filename) into the session.
> pkg load optim # (note optim, not optim-1.4.1.tar.gz)
I am doing this on a Ubuntu Desktop, but the process ought to be similar on other Linux machines.
Installing Packages
1. Install the package "liboctave-dev" using the GUI Software Center, Synaptic Package manager, or the command line as:
sudo apt-get install liboctave-dev2. Go to Octave-Forge site to download the "tar-gz" file for the package you want to install. It tells you how up-to-date your Octave has to be, and what other packages you need.
Dependencies: Octave (>= 3.6.0) struct (>= 1.0.10)I downloaded the struct-1.0.11.tar.gz and optim-1.4.1.tar.gz files.
3. Open an Octave session in the location where you saved the zipped files. At the prompt type:
> pkg install struct-1.0.11.tar.gz
> pkg install optim-1.4.1.tar.gz
If there are no errors, then the package is successfully installed.
UPDATE October 2018: With a newer Octave installation [ > 3.4.0], you can merge the download and install steps by a command like:
> pkg install -forge struct
It does the downloading, installing, and cleaning up for you.
Loading Packages
When you want to use a function from a package in an Octave program, you first have to load the package name (not the filename) into the session.
> pkg load optim # (note optim, not optim-1.4.1.tar.gz)
To unload a package
> pkg unload optim
Miscellaneous
Q: How do I find out what packages I have?
A: > pkg list
Package Name | Version | Installation directory
--------------+---------+-----------------------
optim | 1.4.1 | /home/sachins/octave/optim-1.4.1
struct | 1.0.11 | /home/sachins/octave/struct-1.0.11
Q: How do I update installed packages?
A: If you have an internet connection, you can update packages from an Octave prompt by:
> pkg update
Q: Where are the installed packages?
A: By default they are stored in the ~/octave/ directory. If not present, it is created the first time you install an Octave package.
