MATLAB: Parfor + large input database for a function inside the loop

Question

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
