How to solve a linear programing in matlab in canonical representation? [closed]

Answer 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 );

Answer 2

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