Parfor cannot serialize data which is too large

I have a parfor loop which calculates eigenvectors as a function of frequency, and stores all of them for post-processing. The size of the eigenvectors is 924*200 (Temp_zvAi for instance), and the size of zuxAi is 924*200*1311. The eigenvectors are complex, and zuxAi is around 3.8GB. Parfor returns the serialization error. How to get around this please? The code looks like below:
parfor fcount=1:Numsam
[Amat,Bmat]=functionof(fcount);
[Temp_zkA,Temp_zvAi]=eigenSolver (jn1,Amat,Bmat);
Temp_zuxAi=Temp_zvAi(1:nA,1:jn1);
zuxAi(:,:,fcount)=Temp_zuxAi;
Temp_zuyAi=Temp_zvAi(nA+1:2*nA,1:jn1);
zuyAi(:,:,fcount)=Temp_zuyAi;
Temp_zuzAi=Temp_zvAi(2*nA+1:3*nA,1:jn1);
zuzAi(:,:,fcount)=Temp_zuzAi;
end

The limit on PARFOR data transfers was removed in R2013a. Please upgrade if you can.
