对MATLAB软件在控制领域的应用进行了详细介绍。内容包括使用DAS工具箱函数和ActiveX控件设计数据采集与控制程序；使用串口I/O流和MSComm控件设计串口通信程序等。每种程序设计方法都提供了多个典型应用实例，每个实例都提供了线路图、详细的程序设计步骤和完整的源代码可供自动化、计算机应用、电子信息、机电一体化、测控仪器等专业的大学生、研究生及相关技术人员学习和参考。 (MATLAB software in the control area of the application in detail. Content including the use of ActiveX controls DAS Design Toolbox functions and data acquisition and control procedures use the serial port I/O design flow and MSComm control serial communication procedures. Each programming methods provide a more typical application, each instance provides a road map, detailed program design steps and the complete source code for automation, computer applications, electronic information, mechanical and electrical integration, measurement and control instruments professional students, graduate students and relevant technical staff to learn and reference.)
