Clear persistent variables of function on worker

Question

0 个投票

I need to clear the persistent variables of a function on all workers after having called it from a parallelized statement.

parfor n = 1 : N
    persistentFunction()
end
spmd
    clear persistentFunction
end

The above will not work because clear cannot be called from an spmd statement.

How can I clear persistentFunction ?

Whenever you issue a clear command at the client, the same clear command is issued on the workers. So you can simply do

clear persistentFunction
