MatLab / Simulink TCP /接收坏数据

Question

我有Java代码将TCP / IP数据发送到Matlab，使用以下代码：

four=tcpip('localhost', 4444, 'NetworkRole', 'client');
set(four,'Timeout', 30);
set(four, 'InputBufferSize', 7688);
fopen(four);
fread(four,1,'double')
ans = 4.4

这一切都按预期工作。当我运行相同的Java代码发送到Simulink Instrument Control Toolbok连接到作用域的TCP / IP接收时，它似乎只在我有一个数据类型为单一时接收数据，但数据的值是2.275。

 Block {
  BlockType               Reference
  Name                    "Data From Java"
  SID                     "1"
  Ports                   [0, 1]
  Position                [120, 246, 230, 294]
  ZOrder                  2
  LibraryVersion          "1.84"
  SourceBlock             "instrumentlib/TCP//IP Receive"
  SourceType              "TCP/IP Receive"
  Host                    "127.0.0.1"
  Port                    "4444"
  DataSize                "[1 1]"
  EnableBlockingMode      on
  Timeout                 "30"
  SampleTime              "0.01"
  DataType                "single"
  ByteOrder               "BigEndian"
}

如何在我的Simulink模型中读取二进制double（float）？
