How to apply multiple inputs to an array of function handles in Matlab?

Question

I have a function handle e.g.

x = @(x)[2*x;x^2;x-13;3*x+2]

Now I can evaluate all functions for a given points say x(1) giving as a result 2,1,12,5. But I would like to provide it with 4 points like so x(1,2,13,1) and get 2,4,0,5. I know I could write my own function to do this, but this seems fairly basic and I suppose a solution exists, but I don't know how to find it in the documentation.

Try x = @(x1,x2,x3,x4)[2*x1;x2^2;x3-13;3*x4+2]; disp(x(1,2,13,1)) 2 4 0 5 — Andrei Davydov

It is documented here: mathworks.com/help/matlab/matlab_prog/… — Sardar Usama

A solution can be like this:

y = @(x)[2*x(1);x(2)^2;x(3)-13;3*x(4)+2]

Then evaluate the function like the following:

y([1 2 3 4])

Then you will get the following result:

[2;4;-10;14]

The second solution would be such as mentioned by @Andrei in the comment.
