tcpip與C++應用程序的Simulink鏈接

-1

我嘗試在我的simulink模型或只是一個m文件和我的C++應用程序之間建立鏈接，但我遇到問題。我真的不明白matlab如何接收數據，以及simulink是以哪種形式發送數據到塊？我想發送像xyz這樣的座標給matlab，並用matlab實時分散座標流。可能嗎？tcpip與C++應用程序的Simulink鏈接

這裏是C++提取碼：（不好意思評論是法語）

   /* Démarrage du listage (mode server) */ 
       sock_err = listen(sock, 5); 
       printf("Listage du port %d...\n", PORT); 

       /* Si la socket fonctionne */ 
       if(sock_err != SOCKET_ERROR) 
       { 
        /* Attente pendant laquelle le client se connecte */ 
        printf("Patientez pendant que le client se connecte sur le port %d...\n", PORT); 

        csock = accept(sock, (SOCKADDR*)&csin, &recsize); 
        printf("Un client se connecte avec la socket %d de %s:%d\n", csock, inet_ntoa(csin.sin_addr), htons(csin.sin_port)); 
        // double buff = 25; 

mxArray *datasend; 
datasend = mxCreateDoubleMatrix(1, 1, mxREAL); 
mlfPrintmatrix(datasend); 

        sock_err = send(csock, T, 3*sizeof(double), 0); 

        if(sock_err != SOCKET_ERROR) 
         printf("Send : %s\n", buffer[0]); 
//printf("send : [10 20 30]"); 
        else 
         printf("Erreur de transmission\n"); 

        /* Il ne faut pas oublier de fermer la connexion (fermée dans les deux sens) */ 
        shutdown(csock, 2); 
       }
