overwriting in a loop

Hi guys,

I'm trying to workout a percentage for button errors using a loop. I have managed to do this but I can't figure out how to stop overwriting my previous loop. Its the last line i'm having trouble with and I'm not sure whether putting this into a matrix is the correct way of saving the percentage.

for i = 1:numel(fields);

for j = 1:numel(fieldsone);

count_rows = height (ButtonError.(fieldsone{j}));

rows = height (my_structure.(fields{i}));

percent = count_rows/rows*100;

percentageError {i}= [percent];

end

end

TIA

You have two for loops with loop counters i and j. You last line is using the outer counter, i. If you want to keep every value, you will need to use both indices. Try something like this

percentageError(i,j)= [percent];

Thank you! This works although I now have a matrix in which each row/column is repeated 8 times, I'm not sure if there is another way to avoid this but I think i'll just get rid of this after :)

If you are getting repeated values, that tells me you can probably get rid of one of your loops.

Why not do

percentageError(i, j) = percent;

This worked the same as the above answer, thank you!
