TCP/IP 接口

使用 TCP/IP 客户端和服务器进行通信

传输控制协议 (TCP) 是位于互联网协议 (IP) 之上的传输协议，也是最常用的网络协议之一。Instrument Control Toolbox™ 对 TCP/IP 通信的支持包括创建客户端和服务器的能力。TCP/IP 客户端支持使您能够使用网络套接字通信从 MATLAB^® 连接到远程主机，以读取和写入二进制和 ASCII 数据。TCP/IP 服务器支持使您能够创建一个网络套接字，用于 MATLAB 和单个客户端之间的通信。

使用 tcpclient 创建一个连接到服务器或硬件并执行读写操作的 TCP/IP 客户端。使用 tcpserver 创建 TCP/IP 服务器。
