How to split an array as argument values in matlab?

In my matlab script, I have a function handler 

F=@(x1,x2)6+2*x1^1+3*x2^2;

This gives me an anonymous function as F that takes 2 arguments and returns the value. I also have an array of values

x = [1 2];

With the above, how can I do

F(x)

In other words, something like F(1, 2) but I want to use x, I don't want to hard code values, and it also needs to work for any dimension size, I don't want to hard code it for 2-dimension like in the above example. Basically what I'm looking for is a way to turn an array into arguments.

Can this be done in matlab?

Thanks

To turn an array into its arguments: first turn the array into a cell array (with num2cell), and then turn the cell array into a comma-separated list (with {:}):

xcell = num2cell(x);
F(xcell{:})

Does this work? 

F=@(x)6+2*x(1)^1+3*x(2)^2;
xx = [1 2];
F(xx)
ans =

    20
