| Abstract: | Due to advantages of its approaching capacity,classifying capacity and studying speed,radial basis function neural network is gathering scholar's ever-increasing attention.Integrative assessment of regional eco-carrying capacity is expressed by using MATLAB tools with radial basis function neural network. The framework,design,simulation and figure output of radial basis function neural(network) of MATLAB are presented.As an example,eco-carrying capacity is assessed in Yancheng coastal wetland region by MATLAB radial basis function method.The result shows that the method has the features of simplicity,credibility and good classifying capacity,and it has a wide prospect of application. |
