User-Defined Functions
Custom function blocks such as MATLAB Function, MATLAB System, Simulink
Function, and Initialize Function
Use blocks from the User-Defined Functions library to extend Simulink® modeling functionality by creating new types of blocks. You can implement block algorithms using MATLAB®, C/C++, and Fortran® code.
Blocks
C Caller | Integrate C code in Simulink |
C Function | Integrate and call external C/C++ code from a Simulink model (Since R2020a) |
Fcn | Apply specified expression to input |
Function Caller | Call a Simulink function |
Initialize Function | Execute subsystem on model initialize event |
Interpreted MATLAB Function | (To be removed) Apply MATLAB function or expression to input |
Level-2 MATLAB S-Function | Use Level-2 MATLAB S-function in model |
MATLAB Function | Include MATLAB code in Simulink models |
MATLAB System | Include System object in model |
Reinitialize Function | Execute subsystem on model or subsystem reinitialize event (Since R2022a) |
Reset Function | Execute subsystem on model reset event |
S-Function | Include S-function in model |
S-Function Builder | Integrate C or C++ code to create S-functions |
Simulink Function | Define a function using Simulink blocks |
Terminate Function | Execute subsystem on model terminate event |
