Communication TCP/IP

Lire et écrire des données via une interface TCP/IP

Le protocole TCP (Transmission Control Protocol) est un protocole de transport qui se superpose au protocole IP (Internet Protocol). Il s’agit de l’un des protocoles réseau les plus utilisés. Le support MATLAB^® pour la communication avec des clients TCP/IP vous permet d’utiliser la communication par sockets réseau pour vous connecter à des hôtes distants depuis MATLAB afin de lire et d’écrire des données binaires et ASCII.

Utilisez tcpclient pour créer un client TCP/IP qui se connecte à un serveur ou à du hardware et exécuter des opérations de lecture et d’écriture.

Communicate Binary and ASCII Data to an Echo Server Using TCP/IP

Set up an echo server and communicate with it using TCP/IP by creating a tcpclient object. Binary data and terminated string data are sent to the server and the server echoes the same data back to the client.
