Pass pointer to function as in C

I'm a C/C++ programmer and am new to MATLAB. May I ask if I could do the below equivalence in MATLAB, where I have a C subroutine that updates one array from the values of another array?

void vec_update(double* vec1, double* vec2)

{

vec2[0] = vec1[0] + vec1[1] + ... ;

...;

vec2[N] = ...;

}

Here is the equivalent MATLAB-style pseudo-code:

function vec2 = vec_update(vec1, vec2)
    vec2(1) = vec1(1) + vec1(2) + ... ;
    ...;
    vec2(end) = ...;
end

Note that in MATLAB you have to specify the modified vector as an output argument.

Many thanks Benjamin, that solves my question!
