How to remove data points above or below a value in an array, nicely!
显示 更早的评论
In my array (PRE_A, imported from a csv), I want to remove any data point over 900 or below 750, so have written the code below. How do I write this in less lines of code?
Thank you :)
PRE_A = PRE_A(PRE_A(:,2) > 750, :);
PRE_A = PRE_A(PRE_A(:,3) > 750, :);
PRE_A = PRE_A(PRE_A(:,4) > 750, :);
PRE_A = PRE_A(PRE_A(:,5) > 750, :);
PRE_A = PRE_A(PRE_A(:,6) > 750, :);
PRE_A = PRE_A(PRE_A(:,7) > 750, :);
PRE_A = PRE_A(PRE_A(:,8) > 750, :);
PRE_A = PRE_A(PRE_A(:,9) > 750, :);
PRE_A = PRE_A(PRE_A(:,2) < 920, :);
PRE_A = PRE_A(PRE_A(:,3) < 920, :);
PRE_A = PRE_A(PRE_A(:,4) < 920, :);
PRE_A = PRE_A(PRE_A(:,5) < 920, :);
PRE_A = PRE_A(PRE_A(:,6) < 920, :);
PRE_A = PRE_A(PRE_A(:,7) < 920, :);
PRE_A = PRE_A(PRE_A(:,8) < 920, :);
PRE_A = PRE_A(PRE_A(:,9) < 920, :);

I think this is what you're trying to do:
GoodRow = ~any(PRE_A(:, 2:9) <= 750 | PRE_A(:, 2:9) >= 920, 2)
PRE_A = PRE_A(GoodRow, :)
Translation:
GoodRow = ~ any (PRE_A(:, 2:9) <= 750 | PRE_A(:, 2:9) >= 920, 2)
Good rows do NOT have any value <= 750 OR any value >= 920, across all columns
