Write one binblock of data to remote host over TCP/IP
Create a TCP/IP client connection called
t, connecting to a TCP/IP echo server with port 4000. To do so, you must have an
echotcpip server running on port 4000.
echotcpip("on",4000) t = tcpclient("localhost",4000)
t = tcpclient with properties: Address: 'localhost' Port: 4000 NumBytesAvailable: 0 Show all properties, functions
Write the values
[1,2,3,4,5] as a binblock in uint8 format.
Write another binblock of data. Write the values
[6,7,8,9,10] as double data.
Since the client is connected to an echo server, the data you write to the server is returned to the client. Read the first binblock of data that you wrote.
ans = 1×5 1 2 3 4 5
Read a binblock of data again to return the second set of values that you wrote. Specify the data as
ans = 1×5 6 7 8 9 10
Close the connection between the TCP/IP client and the remote host by clearing the object. Turn off the
clear t echotcpip("off")
t— TCP/IP client

data— Numeric or ASCII data
Nnumeric array | character vector | string scalar
Numeric or ASCII data, specified as a 1-by-

writebinblock(t,1:5,"uint8") writes the values
datatype— Size and format of each value
Size and format of each value, specified as a character vector or string.
datatype determines the number of bytes to write for each value
and the interpretation of those bytes as a MATLAB data type.
writebinblock(t,1:5,"double") writes the values
[1,2,3,4,5] as double data.
