What Simulink C Function Blocks does

Simulink C Function Blocks configures C Function blocks for calling legacy or custom C/C++ code in Simulink. Use it when defining inputs, outputs, parameters, or C++ class instances with the SymbolSpec API.

Simulink C Function Blocks is cataloged under AI Engineering on DirSkills. Simulink C Function Blocks comes from a repository tagged agent-skills, claude-code, codex-plugin, engineering-agents and github-copilot.

Documentation

README

Excerpt

C Function Block Configuration

When to Use

Calling or wrapping C/C++ code or libraries in Simulink
Creating, configuring, or using a C Function block
Integrating custom code, legacy code, or external C/C++ into a model
Integrating a C++ class into a Simulink model or test bench
Configuring inputs, outputs, or parameters for a C++ algorithm in a block

When NOT to Use

Building general Simulink models without C/C++ integration
MATLAB Function blocks (Embedded MATLAB) — those use MATLAB syntax, not C/C++
Code generation workflows (Embedded Coder, Simulink Coder) — this skill is for simulation-time configuration only
