MATLAB: How to combine several functions

combineconcatenatefminconfsolvefunctionsMATLAB

i have the following functions:
f1 = @(k1)108.4*k1
f2 = @(k2)108.4*k2
f3 = @(k3)108.4*k3
f1,f2,f3 are automatically generated, and can be very different. i would like to have a unifying function
f = f1 + f2 + f3
and i want to call f in solvers such as fsolve or fmincon.
Thank you !

Hint:
f1 = @(k1)108.4*k1;
f2 = @(k2)108.4*k2;
f3 = @(k3)108.4*k3;
sumf = @(k1,k2,k3) f1(k1)+f2(k2)+f3(k3);
sumf( 1, 2, 3 )
ans =
650.4000
or
sumf = @(k) f1(k)+f2(k)+f3(k);
sumf( 2 )
ans =
650.4000
