Dear all, the idea was to extract different length of vector from a different cell container as demonstrated at the code below. However, I wonder if we can achieve the same procedure using CELLFUN instead. I really appreciate for any tips.
Thanks in advance
Data_CELL = {randi(9, 10,1),randi(9, 6,1),randi(9, 12,1),randi(9, 12,1)};
Extracttill=[4 4 10 9]';
ExtractedData=cell(4,1);
for f_x=1:4
data=Data_CELL{1,:};
ExtrcFUntl=Extracttill(f_x,1);
ExtractedData{f_x,1}=data(1:ExtrcFUntl,:);
end

Here is a "hidden-loop / one-liner":
Data_CELL = {randi(9, 10,1),randi(9, 6,1),randi(9, 12,1),randi(9, 12,1)};
Extracttill=[4 4 10 9]';
endExtractedData = arrayfun(@(k) Data_CELL{k}(1:Extracttill(k)),1:numel(Data_CELL),'un',0)
