MATLAB: Is the HDL code for the division operation not bit-true with Stateflow

Why is the HDL code for my division operation not bit-true with Stateflow?

Best Answer

The HDL code generated from the division operator in Stateflow’s Classic Action Language will not always be bit-true. The semantics of Stateflow division perform integer division. The chance of a mismatch is greater if the division is part of a larger expression, such as X = A - B/C. The generated HDL code will contain greater numeric precision than is retained by Stateflow.

To work around this issue, use the MATLAB Action Language in Stateflow.

char arrays support indexing. Also, string is the name of MATLAB built-in function, so I named the name of the variable to 'str'

str = "This should really be in the MatLab core!";
%convert to character array
b = char(str); % you can simply use char()
ba = length(b);
%get index of "in the"
k = strfind(b,"in the");
stringbuilder = b(k:end);
stringbuilder = string(stringbuilder); % convert back to string

Result

>> stringbuilder
stringbuilder = 
    "in the MatLab core!"

MATLAB: How to get current path in a stateflow？

You should look into Stateflow Animations. It will highlight the latest path taken in blue during simulation, and the last path taken when simulation is stopped.
