How to EFFICIENTLY extract different length of vector from a different cell container?

3 visualizaciones (últimos 30 días)
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

Thanks for the heads up. However, using CELLFUN make the overall code more compact, although I think it may consume the processing time.

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)

Hi Jos, Thanks for the quick reply and awesome solution. Really appreciate it.
Btw, what do you mean by Do you not want to extract the values from 1 until a specific value, rather than a single value?. Your solution above does answer my original question actually.
