linprog. Alsway the answer is 0.

Whatever arrays i use with linprog the only answer it gives me is 0.

Here is an example code:

clc
f = [ 12 ; 7 ];
b = [ 10.000 ; 16.000 ; 0 ; 0];
A = [ 2 , 1 ; 3 , 2 ; -1 , 0 ; 0 , -1 ];
x = linprog(f,A,b);

Not these arrays. I'm sure we can come up with others as well.

f = [ 12 ; 7 ];
b = [ 10.000 ; 16.000 ; 1 ; 1];
A = [ 2 , 1 ; 3 , 2 ; -1 , 0 ; 0 , -1 ];
x = linprog(f,A,b)

Optimal solution found.

x = 2×1

-1.0000 -1.0000
