Function with multiple inputs to function with vector input

In this answer, I found my problem and a partial answer. However, In my case, I have a

f = @(z1, z2, ..., zn) ...

and I would need to unwrap a vector z = [z1, z2, ..., zn] instead:

f = @(z) ...

How can this be done?

For clarity, the original answer only deals with 2d vectors, but I may not know the size of mine.

Please show the function.

f=@(z1,z2,z3) z1+z2+z3;
f(1,2,3)

ans = 6

a=1:3;
b=num2cell(a);
f(b{:})

ans = 6
