用dfb激光器产生混沌型信号的matlab模拟程序(Dfb lasers produce chaos with signal matlab simulation model)

在文本文件中嵌入MATLAB代码并运行返回结果 类似在HTML中嵌入PHP和ASP代码，本函数实现在文本文件中嵌入matlab代码并运行！ 主要作用以及价值： 在文本文件中嵌入matlab代码，并可以直接运行该文本文件 根据matlab变量的当前值，实时修改文件文件中相应的数据 目前具有如下功能： matlab代码使用必须包含在< >符号中，中间的内容都被解析为matlab代码 matlab代码可以放在文本的任意位置，你想放在什么地方都可以 matlab代码允许被文本分割而不连续书写，比如循环语句 fprintf(fid_target,...)函数用来向文件中写入字符，目前还比较麻烦 有待改进的方面有： 在文本文件中增加对matlab function的支持 简化变量输出，目前只能fprintf(fid_target,...) 目前是M脚本完成功能的，后期会提供M函数(MATLAB code embedded in the text file and run return results Similar PHP and ASP code embedded in HTML, the function matlab code embedded in the text file and run! A major role as well as the value of: Matlab code embedded in the text file, and can be run directly on the text file Modify the data file file based on the current value of the matlab variables, real-time Currently has the following functions: matlab code uses the symbol in the middle of the parse matlab code must contain matlab code can be placed anywhere in the text, where you want to put matlab code allows text segmentation without the consecutive writing, such as loop statement fprintf (fid_target, ...) function is used to write characters to the file, there is too much trouble Areas for improvement: Increase support for matlab function in a text file Simplify variable output, can only the fprintf (fid_target ...) M script completed, late M function)
