How to create an array in simulink?

Hello! I would like to create an array with zero values, but i would like to define the array size from external port. So the array would be variable-size. I shouldn't use any MATLAB function. Maybe it would be a proper solution, if I could save the size as a global variable, and I could define the array in a Constant block. Is it possible? Or somebody has any idea for the solution of this problem? Thanks!

You can have a workspace variable say

A=5;

and use

zeros(1,A)

as the value in constant block.

But unfortunately, its not a workspace variable. The size is crounted by a subsystem in simulink. If i wanted to load from workspace it should be run before this size is used as a workspace variable.
