Sending data via udp. Would appreciate help with the proper way of converting a cell array containing char, string, double to ASCII data

Hello!

I have to send the information contained in the attached file DATA.mat to another program (it's running on the same PC for testing). I'm using an UDP-Client/Server and the main program expects the following format (pause is used because the data is normally generated continuously) :

DATA {1,1} \t DATA {1,2} \t ... \t DATA {1,30} \n

...

DATA {end,1} \t DATA {end,2} \t ... \t DATA {end,30} \n

I have managed to do this but it is so ugly that I might get a stroke. I would be very happy if somebody can show me a better way to do the '%convert' part!

My code:

if  ~isempty(instrfindall)
    fclose(instrfindall);
end
load('DATA.mat')
udpMonitor = udp('localhost',9098,'LocalPort',9099, 'InputBufferSize',100000);
fopen(udpMonitor);

[index5_max, ~] = size(DATA);

for index5= 1:index5_max
    
    %convert
    AnMonito= string(DATA(index5,:));  
    AnMonito= strcat(AnMonito(1),"	",AnMonito(2),"	",AnMonito(3),"	", ...
        AnMonito(4),"	",AnMonito(5),"	",AnMonito(6),"	",AnMonito(7),"	",AnMonito(8),"	", ...
        AnMonito(9),"	",AnMonito(10),"	",AnMonito(11),"	",AnMonito(12),"	",AnMonito(13),"	",AnMonito(14),"	", ...
        AnMonito(15),"	",AnMonito(16),"	",AnMonito(17),"	",AnMonito(18),"	",AnMonito(19),"	",AnMonito(20),"	", ...
        AnMonito(21),"	",AnMonito(22),"	",AnMonito(23),"	",AnMonito(24),"	",AnMonito(25),"	",AnMonito(26),"	", ...
        AnMonito(27),"	",AnMonito(28),"	",AnMonito(29),"	",AnMonito(30));    
    AnMonito=convertStringsToChars(AnMonito);
    %sent
    fwrite(udpMonitor, [double(AnMonito) 10]);
    pause(0.1);
end
fclose(udpMonitor);

strData = string(DATA);
for row 1:size(strDATA, 1)
    strrow = strjoin(strDATA(row, :), '\t') + char(10);
    fwrite(updMonitor, char(strrow));   %Maybe you can pass string directly to fwrite. If not pass char. Converting to double is a waste of time.

Thank you very much!

I will check out passing the string directly.
