Installation of multiexp, the text-based program

You can simply download the binary program for your operating system, and put it into a suitable directory, included in the PATH.

1. Download the compiled program: open the multiexpfit page, select Download, select multiexpfit (not multiexpFD), select the compiled program for linux or windows.
2. rename it multiexp, for Linux, or multiexp.exe for windows
3. move the file in a suitable directory, for example /home/myname/bin/ for Linux or c:\myname\bin\ for windows.
4. add the directory to the path. For Linux, add the following line to the file .bashrc in the home directory:
   PATH=$PATH:/home/myname/bin
   For windows, add the following line to the file AUTOEXEC.BAT in c:\:
   PATH=%PATH%;c:\myname\bin
5. Optional operations (you can stop here). Create a batch file for easily run multiexp. For Linux systems, create a text file named multiexp.sh, containing the following text:
   cd $(echo $1 | sed 's/\/[^/]*\.fcn//')
/home/knoppix/bin/multiexp $(basename $1) fit.log 2>fit.err
Then, associate the file extension to it. For my KDE: Settings/Control center/KDE Components/File associations; Add/application + multiexp fcn/add .fcn, icon, multiexp.sh. Remember to set the property of multiexp.sh to "Run in terminal". For the icon, you can use this one:
   For Windows users, the icon can be this one:

Compilation of multiexp, the text-based program

Installation of multiexpFD, the graphic user interface

The multiexp program can work with a text-based interface. The low-level user can require a graphic user interface, with a lot of buttons, menus, windows and so on, that interfaces the user with the program. This is the purpose of multiexpFD.

1. Install multiexp program.
2. Download the Java RE from sun

   PATH=$PATH:/home/something/java/others/bin
   For windows, add the following line to the file AUTOEXEC.BAT in c:\:
   PATH=%PATH%;c:\something\java\others\bin
4. Download the jar file: open the multiexpfit page, select Download, select multiexpFD, select the .jar file.
5. Download also the jar files of the package JSci. Put all the jar files with the multiexp.jar file.
6. Create a shell script. For windows, put the following line in a file named multiexp.bat:
   java -jar c:/something/multiexpFD/jars/Multiexp.jar %1
   Use the full path also for java if it is not included in the PATH
7. Create a link on the desktop.
8. Set the file association for the .mex files. Use the icon for Linux, and the icon for Windows.
