I'm given these objective functions:
Objective function
Minf = 55x1 + 90x2 + 105x3 + 55x4 + 85x5 + 120x6
X1,x2,x3</ 0.5
Minf = 65x1 + 100x2 + 115x3 + 55x4 + 85x5 + 120x6
X1,x2,x3 >/ 0.5
and these constraints:
Inequality/constraints
C1: x1 + x4 >/ 0.9
C2: x2 + x5 >/ 0.7
C3: x3 + x6 >/ 0.3
Nonnegativity: Xi > 0
X1 + x2 + x3 </ 0.5
X1 = 0.8
X2 = 0
X3 = 0.3
X4 = 0.1
X5 = 0.7
X6 = 0
F=140.50
>/0.5
X1= 0.08
X2 = 0
X3 = 0.3
X4 = 0.1
X5 = 0.7
X6 = 0
F= 151.50
And told fmincon or fminsearch would be the easiest way to solve. Any suggestions?

Since the constraints and objectives all look linear, linprog would be ideal.

How do you code this for this many variables though?
