Input

Description

Loads input data from a workspace for a simulation.

Category: Data Import/Export

Settings

Default: Off, [t,u]

On

Loads data from a workspace.

Specify a MATLAB^® expression for the data to be loaded into the model from a workspace. The Simulink^® software resolves symbols in the expression as described in Symbol Resolution.

See Load Data to Root-Level Input Ports for information.

The Input parameter does not load input data from a data dictionary. When a model uses a data dictionary and you disable model access to the base workspace, the Input parameter still accesses simulation input variables in the base workspace.

Off

Does not load data from a workspace.

Tips

If you use a Simulink.SimulationData.Dataset object that includes a matlab.io.datastore.SimulationDatastore object as an element, then the data stored in persistent storage is streamed in from a file. For more information, see Load Big Data for Simulations.
You must select the Input check box before entering input data.
Simulink software linearly interpolates or extrapolates input values as necessary if the Interpolate data option is selected for the corresponding Inport.
The use of the Input box is independent of the setting of the Format list on the Data Import/Export pane.
For more information about using the Input parameter to load signal data to root-level inputs, see Load Data to Root-Level Input Ports.
