I have a 39801x7 array. I want to keep any row of data where is there is a value less than -5 or greater than 5 that the row of data will be kept. I have done the code below but it only does it for column 7 and not all columns. I would like to know what I am doing wrong.
a is the 39801x7 array
for i = 1:7
A1 = a(a(:,i) <= -5 | a(:,i) >= 5 , :);
end

mask = any(a <= -5 | a >= 5, 2);
A1 = a(mask,:);
