How does on create a vector of class based on class name given as string?

Suppose I have a function that should create and return a vector of a certain class where the class name is passed in as a char array (i.e. string). Is it possible to do this in MATLAB? It's certainly possible if you hard-code in the class name. But I would like to be able to pass into the function the name of the class I want to create an array of. The function prototype look like this:
%vector_size is the number of elements in the vector
%element_type is the type of element the vector will initially contain (a class)
function vector = createVector(vector_size, element_type)
And suppose I have a hypothetical class called ElementA, I would create a vector of ElementA with 5 elements like this:
myvector = createVector(5, 'ElementA')
How could one go about doing this?

>> A = [1,2,3]
A =
1 2 3
>> class(A)
ans =
double
>> B = cast(A,'uint64')
B =
1 2 3
>> class(B)
ans =
uint64
EDIT: use cast instead of typecast, as per Walter Roberson's suggestion.

Yes, in this case cast is probably the best answer. I will edit and add this.

You might be able to use
zeros(1, vector_size, element_type)
