Hey,
I am using parfor which loops over a function. That function has two very large dictionaries which I want to copy inside the workers for speed.
Testp = parallel.pool.Constant(Test);
Test = 1;
Testp = parallel.pool.Constant(Test);
parfor ab = 1:2
GG(ab,:) = example(Testp);
end
function [out] = example(Const)
out = Cons.Value;
end
This doen't work on my Matlab which has parallel and access to 5 cores on local. This is the error:
Undefined variable "parallel" or class "parallel.pool.Constant".
Any help?
Thank you, Fary

That facility was introduced in R2015b. Either upgrade or else look in the File Exchange for Worker Object Wrapper
