- How Generated Code Stores Internal Signal, State, and Parameter Data
To calculate output data from input data, the generated code must store some internal data in memory, such as block state data and nonscalar parameter data. - Data Structures in the Generated Code
The code generator uses data structures in the generated code to describe the model fully and store data, such as signal and states. - Data Stores in Generated Code
Use a data store to explicitly model a piece of shared global data in the generated code. - Parameter Data Types in the Generated Code
Optimize the generated code and generate code for specific processors by controlling the data types that store parameter data in computer memory. - Generate Local Variables with Localizable Storage Class
For signals, if possible, generate variables that are local to functions rather than in global storage. - Share Data Between Code Generated from Simulink, Stateflow, and MATLAB
Define data shared between Simulink, Stateflow, and MATLAB. - Air-Fuel Ratio Control System with Fixed-Point Data
Optimize the code generated for an air-fuel ratio control system by using fixed-point data types. - Finely Control Data Representation by Writing TLC Code for a Storage Class
For advanced control of data representation in the generated code, create custom storage classes by writing TLC code.
