How to solve optimization problem?

Dear All,

I have optimization tool box. Could you help me in solving these two optimization problem?

(1)

subject to the constraints

.

(2)

subject to the constraints

, , , ,

.

For the first one:

fmincon() with lower bound 0, upper bound infinity, Aeq = ones(1,6), beq = 1 . And minimize the negative of the expression that you need to maximize (so basically change all those subtractions into additions.)

For the second one: nearly the same but with changes to the lower bound and upper bound.

Thanks.
