其中，子目录《数字信号处理题解及电子课件》_MATLAB程序包含了完成该书的习题参考答案时所用到的MATLAB程序，直接运行这些程序可给出相应习题参考解答的结果。用MATLAB编写的程序的名称由“ex”开头，接下来是所在的章、习题序号及该习题中MATLAB程序的序号，如ex_01_06_1，指的是第1章第6题的第1个程序。(Among them, the subdirectory " digital signal processing solutions and electronic courseware title" _MATLAB The book contains a complete reference to answer the exercises used by the MATLAB program, these programs can be run directly gives a reference to answer the result of exercise. MATLAB program with the name written by the " ex" at the beginning, followed by the host of the Chapter, and the number of exercises exercise program in MATLAB serial number, such as ex_01_06_1, refer to Chapter 1, Article 6, paragraph 1 of the title process .)
