f = @(x,y,z)(x+y+z);
or
f = inline('x+y+z', 'x', 'y', 'z');
or
function f = myfun(x,y,z)
f = x+y+z;
return
give all
>> f(1,1,1) = 3

you can write any function you want - I just showed you some basic examples - such as f = @(x,y,z)(2*x-4*y+pi*cos(z)). As I understand, you want to optimize your function, so you shold take a look at the optimization toolbox.
