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?

How do you code this for this many variables though?
