setExternalInput

Set external inputs for a simulation through SimulationInput object, in

Syntax

in = in.setExternalInput([t, u1,..uN])

in = in.setExternalInput(ds)

in = in.setExternalInput(ts)

Description

in = in.setExternalInput([t, u1,..uN]) allows you to directly specify numerical arrays as inputs to a model if a model has root inports.

in = in.setExternalInput(ds) allows you to directly specify dataset objects as external inputs to a model if a model has root inports.

in = in.setExternalInput(ts) allows you to directly specify timeseries object as external input if a model has a single root inport.

Examples

Set Numerical Arrays as External Inputs Through a Simulink.SimulationInput Object

This example shows how to set numerical arrays as external inputs.

Open the model

open_system('sldemo_mdlref_counter');

Create a SimulationInput object for this model.

in = Simulink.SimulationInput('sldemo_mdlref_counter');

Prepare external inputs.

t = (0:0.01:10)';
u1 = 5*ones(size(t));
u2 = 10*sin(t);
u3 = -5*ones(size(t));

Set external inputs to the model.

in = in.setExternalInput([t, u1, u2, u3]);

Simulate the model.

out = sim(in);
