% Dear Users,
% My problem and simple script are as below:
clear all
clc
nrow=5;
ncolumn=3;
maxinfeas=1;
Infeasibles=zeros(nrow,1);
A=[-1 5 6 ; 4 2 3 ; 9 -7 1 ; 7 3 8 ; 4 0 1];
B=[75 60 90 ; 80 150 65 ; 20 10 40 ; 70 30 80 ; 100 20 35];
for nr=1:nrow
for nc=1:ncolumn
if A(nr,nc)>0 && B(nr,nc)<=100
Infeasibles(nr)=0;
else
Infeasibles(nr)=maxinfeas;
end
end
end
% Although expected matrix is Infeasibles=[1;1;1;0;1], Matlab adjusts it as Infeasibles=[0;0;0;0;0]
% How can I correct the code?
% Thanks a lot!

Infeasibles = any((A<=0) | (B>100),2);

Sure, just update your original code, changing the line:
Infeasibles(nr)=0;
To:
Infeasibles(nr)=max(0,Infeasibles(nr));

You can write
idx = ~(all(A > 0, 2) & all(B < 100, 2))

Isn't it possible to put it into a for loop. It is more convenient for my whole script.
