Other MathWorks country you can specify these properties explicitly. Type. complexity, and type. I have a Simulink model where I need to create an array based on two integers, say n and m. n and m are results from previous Simulink calculations and they change at each time step. Simulink functions are the functions used in Matlab for simulation and modeling purposes. The statement defines an input argument, vals, and Sorry for it's a silly question, but im still new with SIMULINK. Another issue to keep in mind is to have specific sample times for the inputs to the MATLAB Function block. 1 Edited: lokender Rawat on 6 Mar 2018 There are numerous ways to call a function in Simulink block: 1. Property Inspector. The MATLAB function executes for simulation and generates code for a Simulink Coder target. Since a Simulink function provides a common text interface to its function definition and a function caller, how you define the function is your choice. check this link Share Improve this answer Follow edited Dec 27, 2016 at 17:05 answered May 12, 2013 at 20:30 NKN 6,378 6 35 54 An S-function is a computer language description of a Simulink block written in MATLAB, C, C++, or Fortran.
