How to input a vector into a multi-variable symbolic function - Error using symfun/subsref

Hi,

I'm trying to generate a series of vectors using a recursive function. Say my initial vector is [1 1], and my function is f((x,y))=(x+1,y+2).

I've defined my function as follows:

syms x y;
f=symfun([x+1 y+2],[x y]);

I then want to apply f to the initial vector, but when I try to use

f([1 1])

I get the error

Error using symfun/subsref
Symbolic function expected 2 inputs and received 1.

How can I apply f to this vector? The issue is that the vector's dimensions vary, so I can't explicitly write

f(x1, x2, ... xn)

Thanks in advance!

okay it's a bit late but maybe someone else could use this

try this:

subs(symbolic_expression, list_of_variables, list_of_values)
