中文说明：此代码包含决策使用。在这些系统中执行的主要任务是采用归纳的方法，对未知的对象的属性的给定值确定适当的分类，根据决策树规则。我们审查决策树学习算法 ID3 算法与实现这应用 matlab 软件
English Description：
This code consists of decision making using .The main task performed in these systems isusing inductive methods to the given values of attributes of an unknown object to determine appropriate classification according to decision tree rules. Weexamine the decision tree learning algorithm ID3 and implement this algorithm by MATLAB
