How to get vector output?

Hy, I would like to know how to get vector output from the function?

for example

x = 0.5
y = 1

f = (1/2)*(x + y )    and out i want:
{answer}
{answer}

i try this:

f = inline('(1/2)*(x + y ) ')
[u v ] = f(x,y)    but this doesnt work

Why u and v ?

Why would you expect a vector out of that equation? That equation is of the form

z = f(x,y)

It is producing a scalar (real or complex) for any pair of scalar inputs.

If you want a vector output, you would have to put in a vector

x = [0.5 ; 0.5];
y = [1 ; 1]
f = 1/2*(x+y)
