It is not compatible with Octave releases prior to 4.2.0. Here are the links used to install the Octave releases tested :

Linux : sources from https://www.gnu.org/software/octave/ ;
MacOS : release 4.4.1 installed with dmg ﬁle from http://octave-app.org/Download.html, releases 5.1.0 and 5.2.0 installed with Homebrew ;
Windows : binaries from https://www.gnu.org/software/octave/.

Matlab / Numerical / fc-amat/ Automatic installation, all in one (recommended)

For this method, one just has to get/download the install ﬁle ofc_amat_install.m Thereafter, one runs it under Octave. This script downloads, extracts and conﬁgures the fc-amat and all the required packages in the current directory.

For example, to install this package in ~/Octave/packages directory, one has to copy the ﬁle ofc_amat_install.m in the ~/Octave/packages directory by using previous link. For example, in a Linux terminal, we can do :

Linux Console

cd ~/Octave/packages
HTTP=https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave
wget $HTTP/fc-amat/0.1.2/ofc_amat_install.m

Then in an Octave terminal run the following commands :

Octave Console

>> cd ~/Octave/packages
>> ofc_amat_install

The optional ’dir’ option can be used to specify installation directory :

ofc_amat_install(’dir’,dirname)

where dirname is the installation directory (string).
This is the output of the ofc_amat_install command on a Linux computer :

1- Downloading and extracting the packages
2- Setting the <fc-amat> package
Write in ~/Octave/packages/fc-amat-full/fc_amat-0.1.2/configure_loc.m ...
3- Using packages :
   ->             fc-tools : 0.0.30
   ->             fc-bench : 0.1.2
with              fc-amat : 0.1.2
*** Using instructions
   To use the <fc-amat> package:
   addpath(’~/Octave/packages/fc-amat-full/fc_amat-0.1.2’)
   fc_amat.init()

   See ~/Octave/packages/ofc_amat_set.m

The complete package (i.e. with all the other needed packages) is stored in the directory ~/Octave/packages/fc-amat-full and, for each Octave session, one have to set the package by :

Octave Console

>> addpath(’~/Octave/packages/fc-amat-full/fc-amat-0.1.2’)
>> fc_amat.init()

If it’s the ﬁrst time the fc_amat.init() function is used, then its output is

Octave Ouput

Try to use default parameters!
Use fc_tools.configure to configure.
Write in ~/Octave/packages/fc-amat-full/fc_tools-0.0.30/configure_loc.m ...
Try to use default parameters!
Use fc_bench.configure to configure.
Write in ~/Octave/packages/fc-amat-full/fc_bench-0.1.2/configure_loc.m ...
Using fc_amat[0.1.2] with fc_tools[0.0.30], fc_bench[0.1.2].

Otherwise, the output of the fc_amat.init() function is

Octave Ouput

Using fc_amat[0.1.2] with fc_tools[0.0.30], fc_bench[0.1.2].

For uninstalling, one just has to delete the directory

~/Octave/packages/fc-amat-full

Matlab / Numerical / fc-amat/ Manual installation

Download one of the full archives (see web page) which contains all the needed toolboxes (fc-amat, fc-tools and fc-bench).
Extract the archive in a folder.
Set Octave path by adding path of needed packages.

For example under Linux, to install this package in ~/Octave/packages directory, one can download fc-amat-0.1.2-full.tar.gz and extract it in the ~/Octave/packages directory :

Linux Console

HTTP=https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave
wget $HTTP/fc-amat/0.1.2/fc-amat-0.1.2-full.tar.gz
tar zxf fc-amat-0.1.2-full.tar.gz -C ~/Octave/packages

For each Octave session, one has to set the package by adding path of all packages :

Matlab Console

>> warning(’off’,’Octave:shadowed-function’);more off
>> addpath(’~/Octave/packages/fc-amat-0.1.2/fc_amat-0.1.2’)
>> addpath(’~/Octave/packages/fc-amat-0.1.2/fc_tools-0.0.30’)
>> addpath(’~/Octave/packages/fc-amat-0.1.2/fc_bench-0.1.2’)
