Using parfor

Hi I'm trying to use parfor this way

   R=zeros(20,20,5);
  parfor (i=1:5,4)
      %Here is a long and complicated computation that outputs a matrix X. This matrix X will vary for different i but can fit within a 20x20 matrix
  .
  .
  .
  R(1:length(X(:,1)),1:length(X(1,:)),i)=X;
  end

But Maltab will not allow me to set R this way.How can I go about this problem? Thanks

Try creating the 2D slice of R locally, and copying that to R(:,:,i).

Yep worked thanks a lot

I changed it by adding

temp=zeros(20,20);

temp((1:length(X(:,1)),1:length(X(1,:)),i)=X;

R(:,:,i)=X;

end
