通过tcpip与C应用程序进行Simulink链接

我正在尝试在我的simulink模型或m文件和我的C应用程序之间 Build 链接，但我遇到了问题 . 我真的不明白matlab是如何接收数据的，以及我应该以哪种形式将数据发送到块中的simulink？我想将像xyz这样的坐标发送到matlab，并使用matlab散布3实时坐标流 . 可能吗 ？

这是C提取代码:(抱歉评论是法语）

/* 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);
                }
