What Is an S-Function? S-functions or system functions provide a powerful mechanism for extending the capabilities of the Simulink ® environment. An S-function is a computer language description of a …

These examples show you how to work with a variety of S-functions or programs that use S-functions, including C/C++ S-functions, Fortran S-functions, S-function Builder, Level 2 MATLAB ® S-functions, …

MATLAB S-function API enables users to use MATLAB language to create custom blocks with the capability of handling multiple input and output ports as well as signals produced by a Simulink ® …

S-functions can be either single or multirate; a multirate S-function has multiple sample times. Sample times are specified in pairs in this format: [sample_time, offset_time].

The application program interface (API) for writing S-functions allows you to implement generic algorithms in the Simulink environment with a great deal of flexibility. If you intend to use S-functions …

A Level-2 MATLAB S-function consists of a setup routine to configure the basic properties of the S-function, and a number of callback methods that the Simulink engine invokes at appropriate times …

An S-function is a computer language description of a Simulink ® block written in MATLAB ®, C, C++, or Fortran ®. C, C++, and Fortran S-functions are compiled as MEX files using the mex utility.

The S-Function Builder block uses wrapper methods to specify the S-function code and properties that generate the corresponding S-function. Use the appropriate wrapper methods to construct the S …

The S-Function Builder block is a Simulink ® block that integrates C/C++ code to build an S-function from specifications and C code that you supply. The S-Function Builder block also serves as a …

Compare and contrast features supported by different types of S-function implementations.
