MATLAB: 2D Array Constant in Simulink

Question

I imported an excel (2 Dimensional) table using the xlsread command. In simulink I then create a constant that poinst to the variable that contains the excel data. The simulink code i'm writting will eventually end up being deployed to an embedded target.

If I make multiple copies of this constant in simulink subsystems will the code generator make multiple instances of this table or will it know that there is only one table.

I don't want to kill my embedded target's memory by using this table the way that i am.

Answer 1

As long as you resolve the constant value to a workspace variable (and not inline the value into the Constant block's dialog parameter), I expect that the two blocks will reuse a single variable.
