Is it possible to enter matlab a string like that:
MAX 140 x1 + 160 x2 +x3
SUBJECT TO
2 x1 + 4 x2 <= 28
5x1 + 5.333x2 -500X3 = 0
x1 <= 8
x2 <= 6

回答1:
check out linprog:
f = [140, 160, 1]'; %'
A = [2 4 0];
b = 28;
Aeq = [5 5.3333 -500]
beq = 0
lb = -inf*ones(3,1);
ub = [8, 6, inf]';
x = linprog( f, A, b, Aeq, beq, lb, ub );

YALMIP will get you closer to what you want. You might also want to look into CVX.
