Vectorize a nested loop

Hi all,
is there a way to vectorize the following loop?
for RIPETIZIONE = 1:10
%for k = 1:size(lambda_tol_vector.Value,1)
parfor (k = 1:size(lambda_tol_vector.Value,1))
%fprintf('Completion using nuclear norm regularization... \n');
[CompletedMat,flag] = matrix_completion_nuclear_GG_vec( ...
A.Value.*double(B), double(B), N, lambda_tol_vector.Value(k), tol);
if flag==1
CompletedMat_parvec{RIPETIZIONE,k}=zeros(size(A));
end
CompletedMat_parvec{RIPETIZIONE,k}=CompletedMat;
end
end

EDITED:
R=10;
K=size(lambda_tol_vector.Value,1);
CompletedMat_parvec=cell(R,K);
B=double(B);
parfor n=1:R*K
[RIPETIZIONE,k]=ind2sub([R,K],n);
%fprintf('Completion using nuclear norm regularization... \n');
[CompletedMat,flag] = matrix_completion_nuclear_GG_vec( ...
A.Value.*B,B, N, lambda_tol_vector.Value(k), tol);
if ~flag
CompletedMat_parvec{n}=CompletedMat;
end
end
idx=cellfun('isempty', CompletedMat_parvec);
CompletedMat_parvec(idx)={zeros(size(A))};
