I have attached a .mat file. It has two columns. In the second column if the values are greater than equal to 1 or if the values are less than equal to -1 the code will take the complete row and I'll get a new matrix. How to do it

load 'D.mat';
D_new = D((D(:, 2) >= 1) | (D(:, 2) <= -1), :);

load D.mat ;
A = D(D(:,2)>=1,:) ;
B = D(D(:,2)<=-1,:) ;
