Scalar Multiplication of different values at same time

I have a function -

[x1 x2 x3] = somefunction(y1,y2);

now i want to multiply the [x1 x2 x3] by scalar value z.

[x1 x2 x3] = [x1 x2 x3] .*z; % Want to do like this which is not valid as per the codde

instead of doing the multiplication individually i want to do the multiplication all at a time.

Is there any way to mulitiplication all at a time.

Assign the values with one output for instance as variable X which consists all the values in it.

No thats not possible, i know you want to vector these different variables and then multiply but it is not possible at present as of now.

Function is not in my hands to control these variables

" i know you want to vector these ... "

What does that even mean??

[Kanchibhotla Chandra Sekhar]

that means inside the function -

xy(1) = x1;

xy(2) = x2;

xy(3) = x3;

and then outside the function - xy.*z

[madhan ravi]

Illustrate what your trying to do with an expected output (meaning

a = 10;
b = 20;
result = a * b 
% which would give 200 

), that's what a valid illustration is unlike yours? , have a hard time understanding what’s your goal. Nobody here can read what's in your mind.

My goal is simple -

i have function with has three different values -

[x1, x2, x3] = somefun(y1,y2);

now i want to do salar multiplication to x1, x2, x3 which are individual variables and want to do the scalar multiplication all at time.

Like this -

[x1, x2, x3] = [x1, x2, x3].*z; % where z is scalar value

which is not possible since the assignment of variable to different variables all at a time.

Is there any possibility to multipliy the variables all at a time.

[per isakson]

AFAIK: NO! However, some do weird tricks with subsref and subsasgn.
