我的模式识别作业，用感知器算法对二维的点进行识别，求出判决函数-operations of pattern recognition, perception algorithm using two-dimensional point of identification, obtained judgment function

这是模式识别中来进行特征变换的程序，比较不错，希望对大家有用。这是我做作业时编写的。-This is the feature pattern recognition to transform the program, quite good, we want to be useful. This is me with my homework when prepared.
