生成されたコード内のストレージ

生成されたコードによる内部信号、状態、パラメーター データの保存方法

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. Generating local variables prevents the code generator from implementing optimizations that remove these variables from the generated code. Local variables improve observability, readability, and are helpful in debugging the generated code.

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.

Reuse Parameter Data in Different Data Type Contexts

Reuse parameter data by creating a Simulink.Parameter object or numeric MATLAB^® variable that you can use in different data type contexts.

Limitations for Block Parameter Tunability in Generated Code

Limitations can prevent a block parameter from appearing in the generated code as tunable, which means you cannot interact with the parameter value after compiling the code.

Access Signal, State, and Parameter Data During Execution

As you iteratively develop a model, capture output signal and state data that model execution generates. Tune parameter values during execution to observe results on the outputs.

Switch Between Sets of Parameter Values During Simulation and Code Execution

Switch between independent sets of values for the same block parameters by storing the sets in an array of structures.
