Hi all, I want to remove specific column from a matrix based on certain condition.

let A be a matrix of order 8*3

A=[20 150 1500; 30 400 375; 75 450 2000; 70 100 400; 45 2500 420; 150 480 300; 142,420,1700; 135, 450 420];

if sum of that column is less than 1000 or greater than 100000 then remove that column. how it can be done.

s=sum(A,1);
A(:,  s<1000 | s>100000)=[];
