In general MATLAB coder will try to put the persistent initialization within the FUNCTIONNAME_initialize function. For example for the following MATLAB code:
if(isempty(myVariable))
myVariable = 5;
end
'myVariable'' is initialized to 5.0 within the FUNCTIONNAME_initialize function.
In this case the variable initialization also consists of a function call to RAND. This is why it is not in the FUNCTIONNAME_initialize . The FUNCTIONAME_initialize function is not intended to contain the implementation of the MATLAB code (in this case the variable initialization is tied to the implementation of the RAND call).
