Hello Marco,
To run multiple timer callbacks in parallel in MATLAB, you can try using the 'parfeval' function from the Parallel Computing Toolbox. This approach allows for non-blocking execution of functions, which can be beneficial in scenarios where you need concurrent timer functionality.
You can refer to the following sample code and see if it helps :
% Initialize parallel pool
if isempty(gcp('nocreate'))
parpool;
end
% Create data queues for communication
dq1 = parallel.pool.DataQueue;
dq2 = parallel.pool.DataQueue;
% Define callbacks to handle incoming data
afterEach(dq1, @(data) disp(data));
afterEach(dq2, @(data) disp(data));
% Start parallel execution
f1 = parfeval(@timerTask1, 0, dq1);
f2 = parfeval(@timerTask2, 0, dq2);
function timerTask1(dq)
for i = 1:3
send(dq, "start T1...");
pause(2); % Simulate long processing
send(dq, "end T1...");
pause(1); % Period between executions
end
end
function timerTask2(dq)
for i = 1:30
send(dq, " start T2...");
pause(0.05); % Simulate shorter processing
send(dq, " end T2...");
pause(0.1); % Period between executions
end
end
Note that you need the Parallel Computing Toolbox for this approach to work.
Consider referring to the following MathWorks documentation to know more
