removing for loop by using cellfun

Could anyone provide information on how to remove the for loop from this line of script:
for i =1:length(Name);
Data{i} = arrayfun(@(j)mean(temp{i}(j,1:bin{i(j))),1:length(bin{i}),'un',1);
end
I have tried:
Data = arrayfun(@(j)cellfun(@(a,b)mean(a(j,1:b(j))),1:lenth(b),'un',1),temp,bin,'un',0);
An error returns:
Too many input arguments.
How would I remove the loop?

I am not sure if arrayfun is much faster than a loop with proper preallocation.

I think a for loop should be faster and definitely more readable in this case.
However, 1:bin{i(j))) has a typo and i(j) doesn't make sense since "i" is always a scalar.

Data = cellfun(@(x,y)arrayfun(@(jj)mean(x(jj,1:y(jj))),1:length(y)),temp,bin,'un',0);
