Matlab: The SOM Toolbox is built using the matlab script language. Since structures and N-dimensional matrices are used, it requires specifically Matlab 5.0 or a newer version. However, since Toolbox is programmed using the "plain" Matlab 5 language, no other Toolboxes are required.
Operating system: The Toolbox has been built in unix environment and uses longer than 8+3 filenames. Therefore we cannot guarantee that it works in environments which do not support long filenames, like MS-DOS or Windows 3.1. Also, since different environments force the use of different kinds of fonts in the Matlab GUI, the graphical user interfaces can loose some of their appeal in environments other than Unix.
