How to find those indices that before and including the maxium value of an cell array?

I have a cell maxtrix(see attachment) and I can label the index of the maxium value(the output only labels maximum value as 1 and others as 0 for each cell ) by using this syntax:

 x = cellfun(@(x) x==nanmax(x),cellmatrix,'UniformOutput', false);

however, I wonder to know how do I find those indices before and also including the maximum value by using cellfun(i.e. the output labels all those values before and including maxium value as 1 and others as 0 for each cell)?

Thanks for your help.

Isn't clear to me just what you want -- how about cutting the sample data array down to a minimal set that can look at visually (10 elements is just as good as 10,000 for coding purposes) and show us both input and an expected output.
