Create MATLAB S-Functions - MATLAB & Simulink (original) (raw)

Main Content

Create custom blocks with 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® model, including matrix and frame signals of any data type.

Blocks

Methods

expand all

setup Specify the number of inputs, outputs, states, parameters, and other characteristics of the MATLAB S-function
Outputs Compute the signals that this MATLAB S-function block emits
Terminate Perform any actions required at termination of the simulation
CheckParameters Check the validity of a MATLAB S-Function's parameters
Derivatives Compute a MATLAB S-Function's derivatives
Disable Respond to disabling of an enabled system containing this MATLAB S-Function block
Enable Respond to enabling of an enabled system containing this MATLAB S-Function block
GetOperatingPoint Return operating point for MATLAB S-function as MATLAB data structure
InitializeConditions Initialize the state vectors of this MATLAB S-function
PostPropagationSetup Specify the sizes of the work vectors and create the run-time parameters required by this MATLAB S-function
ProcessParameters Process the MATLAB S-function's parameters
Projection Perturb the solver's solution of a system's states to better satisfy time-invariant solution relationships
SetAllowConstantSampleTime Specify sample time behavior and tunability for S-function blocks with port-based sample times
SetInputPortComplexSignal Set the numeric types (real, complex, or inherited) of the signals accepted by an input port
