GDAT - A collection of software tools on grey-based approaches supported by MATLAB

This paper presents a software package on grey-based approaches named a GDAT (grey-based data analysis toolbox). In recent years, a lot of new grey-based approaches are suggested and applied to, and then the users will demand more evolutionary tools. This package covers grey relational analysis, grey incidence analysis, the grey arithmetic operation, the grey lattice operation, whitening functions, grey structural modeling (GSM), grey classification network (GCN), the grey K-means and grey-rough approximation. These tools are developed by MATLAB with powerful scientific functions, graphic support and various kinds of data-importing support. Components of the current GDAT version and some demonstrations with screen-shots are presented in this paper. The advantages of the proposal include: the GDAT components are free of use, some script codes are on public for use and the latest grey-based models are implemented.
