Hi, I want to run a Simulink model from .m file with sim() function. My Simulink file has inports and outports.
Let's suppose for example that "A" is the inport and "B" the outport. I tried this code:
clear all; close all; clc;
A=1;
B=sim('simulink_file');
But in the workspace I can see that B is 1D array [0 0.2 0.4 ... 10]. In other words that means that the output generated is the time of the simulation.
What is the correct way to give the inputs and set the outputs for the simulation with "sim()" function?

Hey,
Did you define the simulation outputs?

Open Output Argument tab to see how it is done..
