I am trying to paralelize my Genetic Algorith Code, using codistributed function of matlab, but shows this error.. UndefinedFunction error was thrown on the workers for 'sizeofChrome_dis_local'. This may be because the file containing 'sizeofChrome_dis_local' is not accessible on the workers. I introduced a number of chromosomes of 8 and genes 2 and use a simple function as ObjFunction= @Sphere.

I appreciate any support information

Here are some lines of the code....

spmd    
    Chrom_dis= codistributed(Chrom, codistributor1d(1));
    Chrom_dis_local= getLocalPart(Chrom_dis);
    sizeofChrom_dis_local= size(Chrom_dis_local, 1);
    for i=1:sizeofChrome_dis_local
        Obj_local(i)= ObjFunction(Chrom_dis_local(i,:)); 
    end
end

In your code, you define "sizeofChrom_dis_local", but then try to loop over "sizeofChrome_dis_local" - note the extra "e". That's probably the problem.
