How to send Table using UDP in MATLAB

Hello, I hope you are doing well. I want to send Table using UDP. How can i do that?

I have write the following code but it does not working. Can anyone help me with that

client_port = 10011;
clientAddress = '192.168.100.202';

% Define the table
C = {5 "cereal" 110 "C+"; 12 "pizza" 140 "B";...
    23 "salmon" 367 "A"; 2 "cookies" 160 "D"};
T = cell2table(C, 'VariableNames', {'Age', 'FavoriteFood', 'Calories', 'NutritionGrade'});


% Open a UDP port
u2 = udpport("IPV4",'LocalPort',client_port);

% Send the data
write(u2, clientAddress, client_port, T);

Save yourself some work and add only tags that are actually related to your question, not 22 unrelated (like image processing) or useless tags such as matlab, matlab code, code, etc.

According to the documentation, the "data" input is:

"Vector of values to write, specified as a row (1-by-N) or column (N-by-1) array of numeric data, string, or character vector."

A table is none of those things.

Also, the order of the inputs is:

"write(u,data,destinationAddress,destinationPort)"

or

"write(u,data,datatype,destinationAddress,destinationPort)"

@Voss How can i write Table using UDP? Can you help me with that to modified the above code?

[Voss]

If the table contains numeric data, strings, and/or character vectors only, then you can write its contents in multiple write calls, where each call writes data only of one class, e.g., by writing one column of the table at a time.

@Voss I understand. Can you please help me in modifiying the code Like i have the cell array. which includes numeric values and strings. I want to write it. How can i modified the write function?

% Define the table
C = {5 "cereal" 110 "C+"; 12 "pizza" 140 "B";...
    23 "salmon" 367 "A"; 2 "cookies" 160 "D"};

[Voss]

for ii = 1:numel(C)
    write(u2, C{ii}, class(C{ii}), clientAddress, client_port);
end
