Optimization Toolbox

I want to use the optimizaztion to optimize a function if form

f = w(1)*a+w(2)*b+w(3)*c;

where w(1), w(2), w(3) are variable and a.b.c are constants.

the constraints are

0< w(1), w(2), w(3) <1
and w(1)+w(2)+w(3)=1

fmincon should be able to handle that no problem.

Tried it did not work tried even the optimization toolbox

can you give me syntax for the function I gave. how do I set the the constraints

0< w(1), w(2), w(3) <1

and w(1)+w(2)+w(3)=1
