I have charts of state flow. When generating a model in code I have a repetition of local variables. How can I avoid this?
An attempt to change the parameters of automatic assignment of names to local variables did not give a result
static boolean_T resultZC0;
static boolean_T resultZC1;
static boolean_T resultZC2;
static boolean_T resultZC0;
static boolean_T resultZC1;

The problem is the following.
If you have a charts state flow inside which is a simulink function and inside the simulink function and again state flows then local variables initialized in the latter are generated with duplicate names. It needs to be checked, but for now the output is like this

Hey @SergMariupol,
Including a sample model along with images of it would greatly aid the community in providing you with better assistance!

When MATLAB Coder or Stateflow generates code for a model with numerous states or outputs, you may encounter repetitious local variable names such as resultZC0, resultZC1, and so on. This is a typical issue. This occurs because the program automatically generates variables with similar names but distinguishes them with suffixes such as 0, 1, etc., which might result in code repetition.
Try to use Data Store Memory in Stateflow
(resultZC(0) = (some_condition); % This replaces resultZC0
resultZC(1) = (some_other_condition); % This replaces resultZC1)
