Our group has produced several toolboxes for Matlab R14 and newer
versions. Earlier versions of Matlab may also work, but they are
Lazy Learning Toolbox for Time Series Prediction
This toolbox is still in development, for example comprehensive help is missing, but the Toolbox is usable and you are welcome to test it.
Optimally-Pruned Extreme Learning Machine (OP-ELM) Toolbox
The Optimaly-Pruned Extreme Learning Machine (OP-ELM) is an improvement of the original Extreme Learning Machine (ELM)  proposed in  by Y. Miche et al.
- A MatLab toolbox is available here in zip format.

SOM+EOF Toolbox for finding missing values
This toolbox needs also the SOM Toolbox. We wish to thank the authors for their great work.
