In contrast to the static interfaces, the modular interfaces allow multiple objects of the same kind. Thus they are well suited for complex applications requiring e.g. multiple classifiers. Currently the only supported modular interface uses python as a front-end. However, the modular octave interface is build by default too and works reliably albeit a bug in octave (octave will crash on exit unregistering global variables).
Examples for python-modular can be found here or in the examples/python_modular directory.
