Abstract: This article introduces NNTool’s function of the neural network toolbox of Matlab, describes how to use NNTool to realise the design, train, analysis and simulate of neural network. On this basis, it takes the prediction of coal blending as an example, setting up a BP neural network to achieve the approximation and simulation of a non-linear function.
