Hi, I came across the following errors when running the parallel codes. If I use 'parfor',matlab will appear this error:Subscripted assignment dimension mismatch. parfor j=1:1000

But if I use 'for',this error will not appear.I'm very confused about this problem.Can anyone help me,please? Thanks.

The code:

X=load('x.txt');
Y=load('y.txt');
XY=[Y,X];
[a,b]=size(XY);
N=10;
inOption.tol = 1e-6;
inOption.maxit = 50;
inOption.bctype = 1; 
inOption.maxcmp = 50; 
inOption.maxvar = a/2;
ptype='ebtz';
inOption.ptype = ptype;
inOption.delta = 0.1;
msc = [2 3 0:0.1:1];
parfor j=1:50
      B=zeros(0,b);
      for i=1:a
          B=[B;XY(randi([1,a]),:)];
      end
      x=B(:,2:end);
      y=B(:,1);
      x=Standardize(x);
      y=Standardize(y);
      ret=POCREPath(y,x,inOption);
      for k=1:13
          fRes=SelectModel(a,ret,msc(k)); 
          lambda=fRes.lambda;
      end 
      retRes{:,j}=POCRE(y,x,lambda,inOption);
end
