Store Variables from for loop to cell array. it only stores the last run

hello I want to store the variables from a 10x75 matrix, to a cell array. but it should not start at (1,1) in the cell array, it has to start at cell (5,2). If I run the code, it'll only store the variables from how_many_NaNs(:,75), to result(:,79). All the other cells are filled with []. Does anyone has an idea how to fix that problem? Thanks for you advice.

cnter = 2
%create header
for j = 1:size(marker,1)
  result(1,4+j) = {marker(j,:)};
end
%store variables
for n = 1:size(how_many_NaNs,1)
     result(cnter,4+j) = {how_many_NaNs(n,j)};
     cnter = cnter +1;
end
end

You can make your question clear with a small example.

hi azzi

just solved the problem. there was a misstake in one line of code...

kind regards

it might be obvious but you might want to nest your for loops.

cnter = 2
%create header
  for j = 1:size(marker,1)
    result(1,4+j) = {marker(j,:)};
  end
  %store variables
  for n = 1:size(how_many_NaNs,1)
       result(cnter,4+j) = {how_many_NaNs(n,j)};
       cnter = cnter +1;
  end
end

here is your original code and it says you'll be running j from 1 to size of marker. then at the end of the j for loop: j = size(marker,1).

then you go into your n for loop with j=size(marker,1). without understanding the data itself to see how_many_NaNs is made up of, wouldn't you want to go through all j values for each n?

hi joseph

yes you are right! thanks! I have to adapt my code.
