This is my code for the above problem but the answer seems wrong? Can anyone tell me the problems?
f = [-0.4, -0.45];
A = [1, 1; -100 -150; -750, -700; -1 0; 0 -1];
b = [7; -650; -4000; 0; 0];
simlp(f,A,b)
ans =
0.0000
7.0000

simlp() appears to be an undocumented internal Simulink function, that has nothing to do with linear programming ?

Linear programming is typically coded in terms of minimization. You want to minimize the costs. But you have expressed your costs as negative, so if simlp() is like most linear programming solvers, you are effectively asking to maximize the costs.
