On the left side and to maintain constant wall temperature lower side of insulation the right side of the convective heat transfer conditions. Specific parameters are: thermal conductivity of the material = 20w/m • k on the side of the temperature t1 = 100 ℃ right side of the fluid temperature tf = 20 ℃ surface heat transfer coefficient h were 1w/m2 • k and 100 w/m2 • k temperature t2 = 20 ℃ left side of the insulation under)

Volterra 级数，用于非线性建模，其中核需要自己确定，还有记忆长度(Volterra series for nonlinear modeling, in which the core needs to set itself, as well as memory length)

读入COMSOL软件所生成的三维mphtxt四面体网格文件，读入相关网格的节点、四面体单元，边界信息。调用此函数时应将包含相关的路径与文件名的字符串作为输入参数。包中包含了一个m函数文件与一个示例网格数据文件。(read the information of 3-d tetrahedron mesh file--*.mphtxt generated by COMSOL. The input parameter is the path and name of mesh file. A matlab source file and mesh file is included in it.)

说明：  模式识别的经典算法之一，感知器算法，用来对模式进行分类，采用matlab编写。(the classic pattern recognition algorithm, perception algorithm, the model used for classification, prepared using Matlab.)

Linear discriminant analysis (LDA) and the related Fisher s linear discriminant are methods used in statistics, pattern recognition and machine learning to find a linear combination of features which characterizes or separates two or more classes of objects or events. The resulting combination may be used as a linear classifier, or, more commonly, for dimensionality reduction before later classification.
