i'm going to print four variable on serial in fact when i run it ;it going to write this four variable in one value . my question is who to print more than one variable on serial and send it to arduino to use it in the same time.this is my matlab gui codes.
global a;
a=serial('COM4');
setpoint=str2num(get(handles.s,'string'));
aggkp=str2num(get(handles.k1,'string'));
aggki=str2num(get(handles.k2,'string'));
aggkd=str2num(get(handles.k3,'string'));
fprintf(a,'%d',setpoint);
fprintf(a,'%d',aggkp);
fprintf(a,'%d',aggki);
fprintf(a,'%d',aggkd);

If you need to run all of that at the same time you need to run miltiple threads. Check out the Parallel computing toolbox for more information: https://www.mathworks.com/products/parallel-computing.html
I see you are running a PID controller so I would first check how long each of these tasks are actually taking using the profiler. If printing, writing, and updating the GUI is faster than you can acquire data and/or actuate your controller, then there is no need to run everything at the same time.
