% Parallel code block

result = myParallelFunction(); % Replace with your parallelized function

end

This enables the simultaneous execution of the specified code block across multiple MATLAB workers, enhancing overall parallelism.

To conclude your parallel computing session, make sure to close the parallel pool using the delete(gcp) command:

delete(gcp);

This ensures the efficient use of system resources.

In summary, getting started with parallel computing in MATLAB involves initializing the parallel pool, utilizing the parfor loop for parallel iterations, managing data communication, and exploring more advanced constructs like spmd.
